I'm sure it is, but a lot of us are conditioned not to identify by previous bad experiences. This site is pretty good, but I know of others where it isn't nice to be female. After a while, you start "not being" female, even if the poll is anonymous. Less pain and anguish that way.
As for me, I'm proud of what I am. I am defiant. Hear me roar. No 12 year old kid on an internet forum is going to intimidate me. I wish more women thought that way.
I would hazard a guess that there are at least three times the number of females here than have voted in this thread, and I'll bet they have looked at the thread.
