While I agree on it being a slur and don’t use it, I also see the futility of the fight.
Right now that is the word, but “idiot” and “moron” are both terms that have gone through the same events as medical terms adopted as insults, causing us to need a new term.
Oh, I just finished Careless People - a very good read that gives a lot of insight (and cemented my decision to cut out Facebook), and one that has gotten me back into reading non-fiction. I hope you’re finding it compelling!
