Should men be allowed to compete in women’s sports?

Men (*) should absolutely not be allowed to compete against women (**) in any physical sports after the age of 10-12.

There is no reason why women shouldn’t be allowed to compete against men if they are good enough, except for combat sports. A woman fighting against a man in the same weight category in wrestling, judo or boxing would have an unfair psychological advantage, as her male opponent would be reluctant to give his all.

(**) Anyone with XX chromosomes
