Is it normal to break a 10 year friendship after one horrible conversation?

Leave it a while and then contact her. Inform her that you have issues with some of her beliefs but you would like to work to overcome those hurdles if that is what you want. 10 years is a long time.

To me, it sounds like she has undergone some theological transmutation & morphed into some religious acolyte. You will never hear the end of it if you give them half a chance.

Thank you for all your responses, I disagree with some but hearing another perspective helped none the less. I have decided to message Sarah telling her that we need to talk about her comments and how upsetting and offensive they were in hopes of resolving this.

Is your friend a "born-again" Christian, because I often find them to be hella weird.

To be blunt. The Bible says homosexuality is a sin. It also states a lot of things people do is a sin. So everyone guilty.

I'm a Christian myself and I have a few gay friends with no issue because the Bible instructs us to not judge others for sins when you are not innocent yourself. It also says to love your neighbor regardless of their life. Jesus loves everyone and at the end of the day while it is a Christian's job to share the good news, what happens next is between that person and God.

Give it time then call her. If your friendship recovers great, if not don't dwell on it.

I see nothing "homophobic" here at all. I'm an athiest and I don't care for homosexuality either, it's quite common for most people. They just don't show it because they'll be shouted down with hateful slurs like "homophobe".

So, she's done nothing wrong, and broken no laws.

That's her belief and it is a common belief to many religions. If you expect everyone to accept your lifestyle or sexual preferences you should also try to accept the point of view on the other side of the wall. Don't try to change someone else's belief because it isn't in accordance to your philosophy. She's your best friend, try to understand her and fix your friendship, you've been with each other for so long.

If she can't respect who you are then you don't need to be her friend, friends except you no matter what, even if they disagree. She was disrespectful about you're preferences. I'm not saying you should end the friendship or that you should keep it, do what makes you happy. Maybe tell her it was upsetting for you and not to do it again.

Seems a hell of a shame for a 10 year friendship to go down the shitter over this.

I think you'll have to hash it out with her. Maybe you can reach an "agree to disagree" situation, where it's understood that some topics are just off limits for discussion. Maybe she's can be entitled to her views, but she's not entitled to offend everyone in the room. So she more or less has to keep them to herself unless invited to share them?
Not sure if she'd agree to that though.

It's a shame, because obviously she's just fallen in with a bad crowd. But I want to think that you won't give up on her, yaknow? Even though you've lost respect for her - that's just the crazy she is now, don't forget the underlying person she's always been.

But if she keeps going with the craziness, there's a limit to how far that can go without hurting the friendship.

Edit: oops Didn't see your responses. How did it go?

Bullshit story. I am bisexual and have never had a problem at Church.

Your "friend", if she exists, is an idiot and misrepresenting what she is learning.

You can remind her that the Bible also says to “love thy neighbor” meaning stop hating people just because of an orientation. Otherwise, I think that is completely worth being upset over

It's okay, Christians are terrible people anyway.

Imo its ok to disagree on certain things. She is young and will likely change her world veiws. But i wouldnt necessarily stop being friends unless youre gay or shes actively being anti gay. Thought/ opinion is not a crime

The only sinning I see in that story is the three of you patronizing the devil's coffee shop.

Don't give up on her, try to save her from this new church. I smell indoctrination.

I can understand the mental pressure that you are going through.
10 years of respect and a lovely friendship you find out this is what she actually is.
Bibles tells you a lots of shit.
It blames women for rape and also supports the woman being married off to the rapist. And, as you said, 2 people being in love is simply love why the discrimination? If god plans was so perfect why dint the god himself prevent this from happening in the first place.
Lets face the truth all religious books are nothing but items of disruptions of peace.

Whereas your friend, whatever she is saying are just what she is being taught by those pedos.

What I think is you should consider a last and a healthy talk.
Talk to her about this. Because this is about your respect. Your self image, you cannot let anyone ruin that. Talk to her, and if she does not accept whoever you are ,your choice and instead calls you a sinner, its better to leave. For you. For your self respect. She is the one making lame and nonsensical statements which you do not deserve in anyway.

This will not be easy I understand but you have to move on.
Somethings are better left halfway.

That was a very assholish thing to say. Even if she does not agree with people being gay, she should still show respect. People can be born gay, and its really not their fault. Even if you don't agree with being gay, you should still show love. The bible itself actually talks about showing love and letting god be the one to judge. Try telling her that.
And I wouldn't end a friendship over one argument.

Its OK to be gay or strait. I love all people no matter if you are gay or strait. I believe all has a place in gods heart. Your friend might not have meant to hurt your feelings. The bible also says no piercings or markings on your body and I have earrings so I did a sin. Everyone has done at least 3 sins in there life. Don't let your friend make you feel like that.

This is her view, I agree it's a distasteful one. But she has the right to have it and she doesn't seem to be the one whose allowing her belifes about sexuality to get in the way of the friendship. It's pretty ironic but in this the one whose being more intolerant here is you. My nan's a Jehovah's Witness and she always goes on about far off stuff like this. The way to change someone's mind is through debate, it's a pretty biggoted an intolerant person who would break up a 10 year friendship over a diversity of opinion.

Be grateful for the times your friend have spent together, accept that her and you are on different paths in life, people don't stay the same forever, they eventually evolve and change, life is too short.

"Religion poisons everything" said the late great Christopher Hitchens

I say just give it some time

Well, she didn't tell you her views for a solid decade. Clearly she cares about you and knew to not bring that up. I think you should still be friends. It doesn't sound like it's too late.

it is not Ok to hate christians idiot. you are blaming her when she is not god.
