Fuck I hate libs. This whole thing is a lesson that this fucking conversation is nothing but transphobic garbage. But they still see it as a positive. Fucking disgusting.
Now 4 kids can't fucking play with their teams. 4 fucking children. What a fucking victory to celebrate.
I'm so sorry to my trans comrades. I will continue to do anything and everything I can to make a the world a safer place for you.
The US military did a study on it. After two years of hormone therapy, trans men and cis men have no differences in performance (trans men might be able to do more sit ups), while trans women run somewhat faster than cis women, but are otherwise the same.
I suspect that difference in running speed would disappear if you controlled for height. I'm kinda tempted to ask the author of the paper for that data.
