I was referring to the comment higher in the thread, but “stupid” is just as bad, which refers to the “mentally slow.” They didn’t choose to be that way. It’s offensive to refer to other people by that term, because it sounds like you’re using someone’s mental disability, their mental slowness, as an insult to other people.

You’re basically saying “you’re acting like a dumb person,” and being “dumb” is a dis-ability, in the most literal and obvious sense. You can’t choose your intelligence level, that’s just how people are born. It’s incredibly offensive to use one group’s disability as an insult towards someone else.

Hey, crazy suggestion: try kindness? Wow.
