First of all, I think this is a generalized statement as not All men can be grouped into one category. If respect is not a integral part of a relationship, run away fast. If you don't get respect and earn it, I believe you'll have a hard time finding the love you need and want. Also, some men could possibly be raised to disrespect and insult women and some women might not have enough self-respect to put a stop to it or walk away. There is no reason anybody should accept bad treatment.
...and that's just my well-informed opinion.
