If I had to say, the category that you fall into probably has much to do with the content that you choose to post. Unfortunately for anyone with a "dissident opinion" on politics etc., there are hordes of virtue signaling attention grabbers looking to attack you any way possible, all in an attempt to silence your opinion. They won't hesitate to doxx you and attack you in "real life," therefore you must protect yourself (and your opinions) with anonymity.

We should all strive to create a world where we can express our opinions freely without fear of repercussions. After all, why bother censoring someone you don't like? If this person you don't like is as wrong as you believe, then allow them to reveal their wrongness as much as possible. If you must censor them, then what is it exactly that you are afraid of?
