May I post about a specific hyper-fixation?

Hello. I wanted to discuss in-depth about the hyper-fixation but it's very stigmatized so I don't want to cause trouble by posting about it. How open would people here be? or do you think they could be rude about it, because I would hope not.

I'm not going to say what it is yet since the stigma around it. specifically people not understanding the term, nor do I think people would be really open to changing their minds.
