When you ask why men do something, you appear to be asking about behaviors you attribute to men. If you think men and women do something, you should phrase it, "Why do some people...?" It won't help you understand men if you ask why men do something that both sexes do. It will help you understand people, if you are aware people, not just men, do it.

Mellors is posting this to show you how it feels to him on your thread. You don't like generalizations about females, yet you think it's okay to make generalizations about males. He isn't trying to bash females, he's trying to make a point and show you how it feels.

What if someone said, "Why do blacks rob and steal?" Attributing this characteristic to blacks specifically attacks black people, when all races of people rob and steal, so you should ask why people rob and steal. Otherwise, it comes across as racist, just as asking about men in the way you did comes across as sexist.

Sorry again, Mellors, but you're helping to make my point as well.
