Time to get back in the gym ladies. The best athlete won.
The dumbest people you know think participating in women's sports just means you have to put on a wig or grow out your hair. They also have to take hormones and meet the requirements the athletic committee decides on. Whatever boost you think testosterone would give you gets neutralized when estrogen is pumped into your system. A lot of men who start losing their test notice that they feel slower and weaker than before.
The movie "lady ballers" was originally going to be a documentary, but when Ben Shapiro and company found out that they actually would be expected to take estrogen and other things that could cause damage to their testosterone production they gave up and decided to make it into a comedy rather than realizing "oh wait, we were wrong about this".
Female athletes take their sports seriously and if trans enter then it's time to step their game up. Usually when trans enter female leagues they get smoked but if you already have a bias against these people you'll ignore every story that shows that biological women destroy them in sports and cling to any story that shows the opposite so you can reaffirm your world view.
