Is it normal to be afraid of different opinions?
Sometimes I get in debates with people and their opinions make me nervous to the point of crying. I'll give two recent examples:
Yesterday, on an anti-SJW page, the admins posted a picture of a random fat girl who said she was a feminist so that everyone could make fun of her. I thought it was basic knowledge of ethics that that's a really shitty thing to do, but the majority of people were saying that it was just fine and dandy to make really rude jokes about the girl's body "because freedom of speech". It made me really anxious that those commenters had such a twisted perception of what I thought was "objective right and wrong", it made me extremely nervous that the world was becoming so evil and perverse.
Today, on a Facebook group, someone was saying that they think the state should have more power over drug addicts and people with mental disorders, that the state should forcibly take them to institutions or hospitals. That really freaked me out, because I think people should have as much freedom as possible, even if it ends up being bad for them (the State doesn't know what's best for every citizen), plus I have a phobia of psychiatric treatment. So I got very scared that this kind of opinion exists and that maybe these people will eventually have the power to put their plans into practice, and I started crying and all.
Is that normal? Any advice? (Just please, don't argue with my political/social views, that's not the point of my post here).
