Actually, the clubs (AC, RCC) seem to be even more overwhelmingly male. I always stick out in a lounge - (quite young, casually-dressed, non-white male). I could also make an argument that I've been the only minority in First Class on my last three flights that I've gotten upgraded (YYZ-YVR, SFO-YYZ, YYZ-SEA) - and there have been very few women on any of these flights in First including red-eyes.
