I heard it has something to do with men being hunters and woman gatherers.
You heard some bogus sexist nonsense, then.

What I think you should do is...While this true of many places one can talk about D&D and RPGs in general, ENWorld seems especially bad about it -- not every start of a discussion is a request for advice. Asking you how you do something doesn't necessarily mean I don't know how to do it or prefer my method. Often I just want to talk about an aspect of playing or running D&D. I do not need or want someone to tell me how to do it "right" or "better." People that automatically instruct rather than discuss come off as close minded and superior.
I'm guilty of this. When someone comes to me ranting, whining, or complaining, I tend to try help them solve their issue. If that annoys them, I get annoyed. Why are you wasting my time--and yours--bitching about something you don't want to do anything about. I've gotten better about this, but I still have low tolerance for whiners and tend to distance myself from them.
I think most people (anecdotal, I have no idea if there is even research on this) tend to err on the side of assuming you don't have the background in an area. They assume a lower level of skill knowledge until proven otherwise. I don't think this is usually done with ill intent.
