Notice, men have never (beyond sarcastically or pruriently) expressed much desire to join women-only groups or clubs. We figure, for the most part, that women want their privacy and some "company of their own kind", from time to time, and it's okay with us. We're really not interested in what's discussed at such things, anyway, just as women are not generally interested in the things men talk about or do amongst each other.
However, women DO seem to evince a desire (through people like Miss Burk) to join male-only clubs and organizations. It almost seems at times to be an extension of childhood, when the girls couldn't wait to be allowed into the boy's clubhouse or tree fort. Perhaps women are just more interested in what we do amongst ourselves than we are in what they do. The drive does, you'll admit, seem to be one-sided.
What I'm really getting to, I suppose, is whether or not men have the same right to gather and do "guy stuff" without the usual strictures imposed upon gentlemen by the presence the opposite sex as the ladies do.
Bottom line: we don't try to join YOUR clubs/organizations/whatever, can't you extend us the same courtesy?
Men are thinking, "why are women so obsessed with what we are thinking?"
Women will do anything to get into our clubs, only to find out that we talk fishing, sports, our swing, and that hot Blonde behind the counter. And why are women so obsessed with what we think.
So we get away.
