I would fight against martial arts ever being used as an example that mixed sex sports can be equal and fair. In martial arts we have a culture of respect and we are not violent people who are attracted to it - there are MMA fighters where tbh a woman might be killed against a man or seriously injured but martial arts are different to say an underground cage fight, very very different. We have an extreme respect for the rules and each other.
As a victim of DV I took up judo for self defence, in a real life scenario my opponent will not follow the rules. I may be able to defend myself better for knowing some moves or how to escape some moves but knowing judo is not going to save my life if I'm struck from behind unexpectedly over the head for example.
In competition and training - we follow the rules, we have referees watching incredibly closely and it's up to us if we want to fight men. Nobody will be forced to compete against a male body if they don't believe that they will survive it or have a chance.
As a PP mentioned - those who won't conduct themselves within the rules and respectfully don't last in this culture. We bow to each other before and after, we shake hands etc - if anyone refused those most basic rules of respect they would be barred from fighting.
We do sometimes injure each other but if we do - we stop, we are concerned for our opponent, we are not delighted with ourselves and carrying on. We want to win, we don't want to cause serious injuries.
As a side note... I've seen more blood from women fighting women in judo than I ever have from men fighting women. I think this says a lot about how people restrict themselves to fight fairly and respectfully
And I've never seen once we leave the mat anyone not behaving respectfully or feeling anything but concerned for an injured opponent.
The few dicks who are proud they broke someone's arm etc - are soon told about themselves and they lose respect for having that attitude and usually leave and enter things like illegal cage fights!
