I Hate When People Act Like They Are Better Than Others

I posted this picture on my profile in another social site with a caption saying that leaves out nobody so I guess everyone's not worth it. Admittedly it's dark.
Then I get two replies one the size of a book about what a horrible person I am and I have no business having people around me and just calling me right down and the other feebly supporting it.

It was a dark thing to post but do I really deserve to be publicly humiliated in a feed because of it?
If I do then why doesn't everyone else? Like I'm the only one who has negativity in me? I don't think I invented it.

What makes those two better then me? The fact that they can stand up big and tall on the Internet to humiliate me because I posted a picture with a negative caption when I haven't posted in months?

I can't even tell them to $uck themselves cause they blocked me. But they're just better then me.
