Are people with autism rude on purpose?

Often times they genuinely don't realize it.

Usually no. I am "higher functioning" so i'm aware of what is considered rude generally, hence capable of avoiding it and also capable of studying and learning body language and facial expressions to help me avoid negative social situations. However, had I been on the lower end of the spectrum I would likely have been too clueless to ever realize certain types of behaviour are rude. To somebody on the lower end of the autism spectrum you can point out a rude behaviour but they might still not correct it because they do not agree that it's rude. They live by their own set of rules and no, that is not to be rude but rather because the brain is wired differently when you are neurodiverse and one great thing about it is that it's harder to fall for peer pressure, for example. An autistic person will often be very blunt because they cant tell the different between "white lies" and regular "bad lies" so they lump all that together as bad or unnecessary and always tell the truth for better and for worse. Many of us learn the hard way that you cannot do that and we correct our behaviour, often by mimicking others or even mimicking fictional characters in some cases, while others just stay the same.

I dont know how to vote on that one, so imma say that autism comes in different stages, and the more potent, the more and more life around them dissolves.

I think it probably depends where they are on the spectrum and the individual. My step son has autism and he can be rude but he's the sweetest kid and I genuinely don't believe it's intentional. He can just be very blunt with how he feels about this or that at times.

My (child) brother with autism throws tantrums, but he does not intend to harm anyone. My (child) brother with Down's Syndrome, on the other hand....

I think abit of both.

Just watch a few episodes of "The Good Doctor" It portrays how someone on the spectrum thinks and behaves.

They usually don't realize it, they are generally not trying to be rude, but they don't have the same mindset, logic that non-autistic people have.

Yes, because they are cranky that they have autism and don’t know how to properly communicate it well.

From what I understand, they physically don't know how to be any other way. It isn't intentional, they just can't read social cues. It's not likely they do it because they think they can get away with it. If they could behave differently, I'm sure they would. Unless they happen to be a sociopath as well. But that would be an odd combination of mental issues.

It's normal for an autistic person, they're literally following the rules of etiquette then you take it as symbolic and not think they're literally the way they are, and they're not rude. Autistic people are gentlemen, and you're lying, all this is lies about autistic people, you know very well they're good, great and perfect literally, you're jealous.

They genuinely don't realize it mostly. I have a few friends who have autism and they're on the high functioning end of the spectrum as in they don't have it as obvious as others do but they still say and do some really hurtful things and get confused when someone gets upset with them so they're mostly unaware that what they're doing is rude.

In lots of ways not really.

I am not rude at all unless someone is rude to me first. I am kind and sugarcoat everything, like I will never criticise someone if they have not shown themselves to be unfavourable by my standards. If someone shows me art or singing etc they have done, or asks about how they look like, I will ALWAYS say, "it's great! I like it!" Because I recognise that opinions are not facts therefore, things such as art, music, appearance etc are always subjective. But if someone is rude to me, I literally want them to die, and don't give a crap about offending them.
