For online interactions, you should absolutely have a zero tolerance policy with people who make you feel bad. As soon as some dipshit starts giving off bad vibes, disengage, block, and move on with your life. Unlike meatspace, there's no way of telling whether someone is actually who they say they are and whether they can be trusted. I don't even mean being some sleeper agent for the feds. Some people have a history that they try their damn hardest to cover up. They aren't part of a real community where they can be held accountable if they choose to be abusive. For your own safety, you should disengage. There's plenty of fish in the sea and plenty of online communities in cyberspace.

I don't know you people, and you people don't know anything about me. And I would like to stay that way. I would treat any one of you who start shit with me in the same exact way as a belligerent drunk in the subway. It might sound harsh, but everyone has their own boundaries. I'm not your buddy, I'm not your friend, and I'm not your comrade. I'm just a complete stranger, no more and no less. But just because you people are all strangers to me doesn't mean I can't joke around with you or that I won't offer my two-cents on what's going on in the world. It doesn't give me license to act like some unhinged weirdo.

If you're insecure and are constantly walked upon in real life like a doormat, start practicing setting up and enforcing personal boundaries in online communities like this one. Trust me on this.
