Why are people that are into politics/religion/animal rights so self righteous?

Question

I've been browsing the sections here and I've realized that most people in R&S and Politics are complete jerks and think they're better/more intelligent than everyone else. And as far as the vegans/vegetarians go, they act morally superior.

What do they think gives them that right?

Answer 1

self image reason.. they try to act smart in their answers to look smart and get the impression of people to look at them smart but when they answer it shows that they are cracked. people more likely act like they are intelligent and know something about this matter because no one sees them or no one is around to look that they are not really smart.

Answer 2

they feel there more lets say informed and it gives the majority of people a purpose for living
