I'm gonna a bit controversial. From a purely sporting point of view if its about a man fighting a woman in a controlled environment? I actually dont have too many issues. However, this geezer needs to take a long hard look at himself and his motivation for going down this career path.
I've come across some great female fighters over the years who i think would have beaten most men in the ring. The rules would have to be very strict and to the point that there would be heavy penalties for rule breaks so probably not a box office hit.
There is the clear domestic abuse argument that has been covered in this thread and I think we all in agreement.
This guys though? Its like a 30years old jacked fighter on steroids saying - I want to fight 12 year old. He has a clear advantage, he knows he has a clear advantage so what's he up to?
EDIT: OK my analogy is a bit extreme but you see the point I'm trying to make.
