I mean, OP asked for insults. You should be prepared to see some you don’t like (which is the point of an insult after all).

Well, yeah, it’s an insult so it’s not exactly meant to be flattering for either the insulted party or the person they are being compared to.

I mean if any intelligence-based insult is, this one certainly is. The thing is it is better to be smart than not, so trying to shut those all down is probably a fool’s errand.

As an autistic I aprove, if you arent saying this to a ND or mentally disabled person.

It absolutely is. Many insults are.
