It’s more recent. Just the euphemism treadmill in action.

Basically, some people are clinically unintelligent out of no fault of their own, and we’d rather they not get caught in the crossfire when insults are being hurtled. The approach to that has been to try and avoid unintelligence-based insults, but it hasn’t worked, because it actually is just better to be smarter.

I don’t really have a better suggestion, though.

You could at least act ignorant rather than trying to logic your hatefulness

Stop arguing about what slurs are okay to use. The only rule around here is to be nice. If someone asks you to not use a word because it hurts them, the nice thing to do is to listen.

Because language is fluid and changes with societal use. We don’t all defer to linguistic norms from hundreds or even thousands of years ago when literally everything about life would be alien to us now.

I’m sure you didn’t intend to post such a nice comment (based on the historical definition of the word)…
