To be fair, they didn’t actually say that what the others called it was smart or correct, just that they did call it that. But given nuance can be deduced from people’s words, I think we can both assume that the person you’re engaging with isn’t playing with a full deck of cards…
You can want to be as specific all you want. Doesn’t mean the person you initially replied to is wrong, especially given there’s a couple of American dictionaries who list that definition. And I’d temper your rhetoric about there being such a divide a bit too, especially when Ohio and Indiana voted for Trump the year he won. Sure seems like there were a bunch of northerners who were thinking along the same lines as those in the south…
Also, no need to apologise for being a prick, you shouldn’t give two fucks about what people think of you here. I mean, why should you censor yourself for some randoms who don’t know you from a bar of soap? We all have opinions, we should be able to express them how we want. We should also expect criticisms of those opinions though.
