First, I googled for like 2 minutes.

And yeah, a trans woman isn't guaranteed to be a male-tier top athlete. She would have had to build her bones and muscles before she went on HRT, like Laurel Hubbard who was an active weightlifter before she transitioned in her 30s.

Women who win competitions are overwhelmingly cis because the whole field is overwhelmingly cis. That doesn't mean it "isn't causing any issues". It is causing issues. I just posted three examples of issues it's caused. And just because there aren't a huge amount of instances of these issues doesn't mean it isn't a problem. We shouldn't just 'let it slide' because it just doesn't come up often.

This isn't an attack on trans people, this is a question of if and how people who have used any body altering drugs can be fairly included in organized sports.
