Ignoring the points of the argument, you have to tell them to “disengage” with nothing else posted in your comment to them. I have a troll following me around every time I talk about a certain topic and the only way to get them to stop (for a brief moment) is to say “disengage.” I’ve made it clear I don’t want to talk to them anymore, multiple times, but still I have to type “disengage” every time they reply to me the same exact bad faith shit they always say.

If you don’t want to deal with them altogether, you have to consider blocking them. The troll I’ve been dealing with has tried to egg me and others into blocking them, they celebrate each time they get blocked. So I also understand if you don’t want to block them, they are miserable people who enjoy feeding on negativity. The fact trolls roam lemmy can dampen your enjoyment, it really does suck.

Gotta go with YDI here. This was posted in a mental health community which has this rule:

All posts and comments must be helpful and supportive. Do not put vulnerable people at risk.

OP was venting about their abusive parents and the mental health problems they struggle with because of that abuse. You were not helping OP. OP’s story resonated with me and I absolutely would not want to read your comment if I were them, I would be pretty offended by it.
