These days you can be bigoted against black or Muslim or gay or transgender people, but not really about Greek statuary or rap music or electric cars or PHP, no matter how strong your opinions on those.
Elsewhere, it's just used in its original meaning
(India? Indian English has a few things still in common use which are obsolete in UK English).
Example UK usage from 50 years ago: the "Barry bigot" doll in S3E5 of Monty Python's Flying Circus (1972; it's a wind-up racist doll).
I couldn't have managed a definition, but on its own I'd take it to mean something like the supposedly 'obsolete' meaning above.
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.
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.
