I love this topic - even though I'm a straight, white male, I always found myself rooting for all-female teams. It's just way more fun when they crush a cocky couple or a super strong all guy team. It completely dumb-founded me as to why Pam and Winnie didn't U-Turn the hockey guys. Sure, there's a chance they might have still survived, but the girls weren't even in the real alliance (seemingly).
I guess it mostly stems from me wanting just regular dude teams to be on the show more, instead of the giant-bicep guys who can lift a truck but can't get themselves from point A to point B (not saying Bates/Anthony were this, they were alright, just not my favorite by any means.)
Even after an all-female team has won twice, the odds are still against them completely - I want another season where there are 4 all-girl teams. Recent seasons have had 3-4 all male teams, but only 2 F/F. What's up with that? At least keep the even ratio of 3-5-3 for Males-Mixed-Females.
