@TheCosyNavyViper and any other doubters: HERE IS THE SCIENCE.
"...even with roughly uniform levels of fitness, the males' average power during a punching motion was 162% greater than females', with the least-powerful man still stronger than the most powerful woman. Such a distinction between genders, Carrier says, develops with time and with purpose."
Also:
"In mammals in general," says U professor David Carrier of the School of Biological Sciences, "the difference between males and females is often greatest in the structures that are used as weapons."
THIS IS WHY any situation in which an adult with XY chromosomes is fighting an adult with XX chromosomes is never a fair fight.
It's not transphobic IN THE SLIGHTEST to not want to sanction men beating women for sport.
