Eminem never said that trans-women shouldn't be allowed to compete in womens-MMA fighting.
Cis-woman.
I could easily take one of many Eminem quotes (I found a few... but not appropriate to post here) and say "Joe never said that."
I'm not taking a stance on one side or another here for the original post, just pointing out a bad argument.
Then I guess we can expect the top womans MMA fighters to all be trans.
Well done!
