The topic is completely happening right now, with everything in the news daily. So, it’s understandable it has him so triggered, he’s on an obsessive rant.
Does he become obsessive about other things, too?
I am not diagnosed but have obsessive thoughts, especially from things/people who upset me. I also unconsciously do repetitive behavior which is just compulsively typing in air with my fingers. It’s something I’ve always done and it doesn’t hinder me or bother me at all.
Some people with OCD perform rituals and feel that something bad will happen if they don’t. I never had this thinking.
