I remember as a little kid in the 70's, going to Fenway Park. It had to have been 85% male. Cigar chomping, beer guzzling, cursing blue collar men. Now it's 50-50, no smoking allowed, sushi and martinis, etc....not blaming the ladies, mind you, just saying times change, and things do too.
I know plenty of true blue female sports fans, but a lot of women who claim to be big supporters or whatever usually just say that because it's a quick and easy connection to make with a guy. It doesn't take long to know they are full of it
Fenway has changed so much now that for a lot of "fans" who buy tickets, the game is secondary to all the other "lifestyle" trappings that are part of the experience now. It's a place to be seen for people, and maybe they'll see a celebrity or two, and text their friends and leave early even if it's a close game...
Give me a real fan that loves the game, I don't care the gender. I just hate the phonies.
