Usually in my "friends" group make fun of each other, and fun of me. But if I make some comment, even if I am answering something that someone said to me, they judge me saying that what I said was unpleasant, that wasn't a joke etc...

I am sure that most of the times this isn't true. I think they judge what I say with a different parameter. It's like this scene from Simpsons

I think that maybe they see me as somewhat inferior, so they think that I have not the right to do certain things...
