If banter on an online forum keeps you up at night, then one of two things is probably going on. 1) You have an unrealistic idea of your place in the world in which all your ideas and opinions are absolute truth and are not up for debate. 2) The reason it bothers you is that you recognize there is an element of truth in what others say that you dont want to admit to yourself.
Don't take things (or yourself) so seriously. You don't even know any of the people on this forum. Why would their opinions bother you so much?
