I too like to imagine being famous one day, and I'm pretty serious about it. I spend far too much time thinking about the things you mentioned in your secret, and yeah, the general view of females is very discouraging and saddening.

Don't let it stop you though; go for your pipe dream. The world needs more awesome female figures.

Although your fandom will probably be a lot smaller than it would be if you were a guy, at least you'll know your fans aren't just in it for the peenor. That should prevent at least some of the hideously OOC RPF.
