I don't want to continue derailing the thread, but will make one more post and leave it.
You can't control what other people post. I would normally follow that statement with "but you can control how you react to it," but clearly this is where you struggle. Everyone knows this, including you. Some of what you describe probably is personal and malicious, but most of it isn't.
People disagreeing with you is simply a difference of opinion. You won't want to hear this, but more often than not you are the first to riddle your retorts with personal insults and condescension. That typically escalates to the back and forth shit that we often see, people stating that the thread has been derka'd, and you going into victim mode.
Once that happens, some people are better at disengaging than others, and again you know that you struggle with that. People who are aware of, and sympathetic to your personal struggles may back away at that point, but expecting or relying on it is not a strategy for success.
If you feel there are specific people following you around and trying to goad you into becoming the worst version of yourself, do what many have done with you and put them on ignore.
