You should be more respectful of other people's intelligence. Not everyone who disagrees with you is brainwashed.
I think a lot of that comes from people thinking the eye-catching memorable views they've read are the most common views. When they're really not and are mire likely just the views of the most passionate 1%.
That was a perfectly respectable critique.
I used to play a lot of RPGs, and I believe that intelligence and wisdom are two separate traits. Not everyone who’s smart is actually wise.
