In 1998, Serena and Venus Williams said they could beat any man ranked outside the top 200 in the men's division. So, little known and 203rd ranked men's player Karsten Braasch took them up on the challenge. Braasch after a night of drinking and smoking with zero practice, destroyed Serena 6-1 and Venus 6-2 in straight sets. The Williams sisters are the greatest female athletes of all time. And they barely made Braasch break a sweat. It wasn't because Braasch was very good. He wasn't. But, as a male, he possesses biological advantages even the best female athletes can't compete against. That's the very reason we established women's sports to begin with. To even the playing field. That shouldn't be controversial. And you shouldn't need a biology degree to understand it.
