From my context: I’ve often heard it used to mean things other than racist, but it always carries a very strong, intentionally hurtful connotation.
I'm questioning whether I should say that now, based on your comment. Could you explain a bit more about what you mean by "intentionally hurtful"? Specifically, intentionally hurtful of whom?
If you meant the second, then I'm condemning myself for being too opinionated, which is probably something I can get away with...
If I said “oh he’s a keyboard bigot” in this context, I would be attempting to be insulting and harmful towards you.
If you said “oh I’m just a keyboard bigot” it comes off as lighter but my context has me tilting my head in curiosity. It wouldn’t have been a word I’d expect someone to call themselves.
I’d sooner expect “keyboardphile” “keyboard zealot” “keyboard maniac”
Again, language is weirdly varied like that. I’m not suggesting any of this is some universal rule.
The difference from my point of view is that the intent of using the word bigot is not to hurt but instead to judge and condemn.
