I can understand not everyone wants to be an educator, especially of more ignorant people but when people say this I do wonder why they are even talking.

Exactly. If you’re not willing to try and educate someone you disagree with, insulting them is no substitute (in fact it’s pretty much the worst course of action re the presumed desired result), just keep quiet, or alternatively go talk to others who already agree with you so you can stroke each other’s egos, lol.
