Exactly what do you hope to accomplish by posting pictures of yourself in the first place? Not trying to be mean I just don't get it. (I sincerely hope you answer this question.) As for your question... They don't think their behavior is O.K. It's [u]DELIBERATELY[/u] antagonistic. They're trying to get a rise out of you. They're trying to get you to post something like this. Hell, they're sitting in their chair laughing their asses off every time they post a disgusting comment even when you don't reply because they get to imagine you reading it and getting upset. People are jerks when they can hide behind a username.
