Not every opinion needs to be respected though.Of course the usual bad breath, nasty looking teeth, hygiene, smoking etc..
Also, not open minded, argumentative, long-winded, overly critical, takes lots of selfies, doesn't respect my opinion even if he doesn't agree with it, not family oriented, too quiet (i hate having to carry a conversation), vulgar speech and materialistic.
Women seem to have a hard time understanding this.
