The first part of this post is completely absurd, but I agree with the second part.
I assure you thats not absurd. I speal only from experience. I started out think everyone was pretty much the same. Women have their own network at work where they gossip about everything, but men are rarely included even if you are at the same level. Plus I can think of countless instances where a female boss felt threatened by me and did everything they could to sabatoge my work. I have seen it with men too, but not as much.
