I personally think women should be able to fight against the men, if they want.
Weight class restrictions in effect, of course.
I guess I'm just a woman's rights type of guy, so I would have no problem watching them take (legal) beatings from a man, from time to time - if they so choose to compete against men professionally.
Before I get blasted too hard... female police officers are trained to subdue male criminals who are often bigger and stronger, so why can't women fight against men in the UFC? Doesn't make sense to me.
If I'm an idiot, so be it.
