To allow Fallon Fox to fight naturally born females or not, that is the question.
Until age 30, Fox was known as Boyd Burton. Born male, Burton lived his life as such, though believing for a period he was gay. He was even married to a female at one point, and has a child. After serving in the Navy, Burton tried going to college but dropped out, and began driving trucks to earn money for gender reassignment surgery, which he had done in Bangkok, Thailand.
Now as Fallon Fox, “she” made her pro MMA debut in 2012, and made quick work of her first 2 opponents, who are natural females. After that, she came out and started to make headlines. Despite the natural body mass and muscular advantages, all of her opponents have been real females, and one of them, Ashlee Evans-Smith, actually managed to beat her.
As time has gone on, Fox has drawn attention from many big names in the MMA, and even a few words from Hulk Hogan. Many of the MMA fighters and personalities say that Fox should not be allowed to fight natural females. Those include Ronda Rousey, Meisha Tate, and Joe Rogan. On the opposite side, Chris Cyborg is willing to fight her.
This presents quite the paradox for the modern day radical feminist. Some will applaud Fox, and say

Others sympathetic to the LGBTQAUPM+ community state the obvious. https://gendertrender.wordpress.com/2014/09/18/fallon-fox-why-hormones-dont-make-a-woman/
