I don't blame her a bit.
Unfortunately, I was watching MMA Hour [I believe] and they asked a group of people at the show their thoughts. Everyone seemed so eager to be progressive and support the transgender person fighting females. Just a scan of the crowd told me that no one had experience in any field of athletics.
And it will be that type of group that pushes the mainstream view of "why shouldn't a full grown man change sexes and fight women."
