You've gotta be so weird about women to fit in with other dudes. Trying to understand women as people and not as some mysterious alien species makes you an immediate outcast.
Fairly benign example: men will frequently complain about how women will "complain about something and then get mad when you tell them how to fix it". Trying to explain the concept of venting (they're doing it right now! They're venting right now about women!) has usually gotten me reactions that range from weird looks and disbelief to arguments that women actually just love not solving problems.
Obvs this isn't as big of a problem as having to put up with men refusing to understand you but it still sucks being expected to participate in it
