Why do people think it's acceptable to be hateful and rude?

I have to ask, why is it that some people believe that it is their right to be allowed to go out of their way to be insulting and highly offensive to others about who they are, and how they live?

From Internet Trolling to open bigotry such as racism, homophobia, religious hate. I honestly don't get it and I really don't understand people that go out of their way to spread it. People that demand to be allowed to use the N-word, or to deny services to gay people, or who want to burn religious items they know are held scared by others. What is it that makes them feel so superior that they think being so offensive to people that aren't like them is an acceptable behaviour in 2017? Do they not realise that such behaviours mark them out as little more than spoilt children throwing a tantrum?

While I know a lot of it comes from the Right, the Left isn't immune to this sort of behaviour either, so it clearly isn't a partisan thing, so again the question is, why do people think it's okay when it's just as easy to be polite to people rather than deliberately obnoxious sometimes to the point of trying to get those that are being provoked to commit violence.

What do you think?
