Please do not take this as me saying women are not physically capable of standing their own against random man off the street.

However, There is an obvious, and definitive, strength, speed, and body mass advantage to male fighters. Ronda wouldn't only get wrecked by Jon Jones, she would get wrecked by literally EVERY male fighter in the UFC, and probably most males trained in combat sports.

there was a tennis player who got shit on for this when he said that Serena Williams was a the best female tennis player, and when pressed why he didn't say tennis player, he said because she wouldn't be in the top 500 in men's tennis. She has the fastest serve in tennis it tops at 170 kmh. John Ishner, the number 33 tennis player in the world, is on record for a 252kmh serve. The idea that women are equal to men when it comes to sports it silly, if they were, there would be female professional athletes playing in sports with men.

But truthfully, most Martial Arts disciplines are terrible at teaching someone to actually defend them self in a fight outside the context of their own disciplines, and IMO, instill a very false sense of security that can potentially lead to serious injury, as you try to fight rather than gtfo.
