But what women is going to go out with the team of 5-6 guys to do that?
Of course that begs the question, would a lot of these problems be lessened if there was simply more women?
You can hardly ask guys to stop forming friendships based on things that will often exclude women. It's going to happen. It's a problem when women find their careers suffering because of it, or when they don't get a chance to form friendships they can enjoy at work. Yes, they can be friends with men, but it's going to be harder when it's a bunch of guys who want to go do things that a bunch of guys do.
These tactics will simply not achieve anything, other than breeding resentment.
