“For many men, insults and mild hazing are how affection is a shown.”

That’s often how you can tell how well men get along with each other. If they’re constantly insulting each other, or “breaking each other’s balls”, in the vernacular, then you know they’re getting along fine.

When men are polite and curt to other men, they probably hate each other.

Of course sensitive snowflakes with low thresholds for emotional pain wouldn’t know that. But they’re not really men so why would they?
