This is the problem. You talk about advantages, etc, then complete ignore the fact that when a trans woman at the Olympics failed to even place, that proves there is no advantage.

You flip-flop between "obvious advantage!" and "because she's 43!" as and when it suits you. You have no coherence in your argument, you just whichever one isn't the one being argued at the time. This shows your dishonesty, and that you're not throwing straight dice.

Hence, you are a transphobe. Transphobia is not just about flinging slurs and insults. You dismiss the idea that trans women are women because of your own internal biases of what makes a woman. You dismiss the evidence presented to the world about trans women in sport because you don't want to admit to being wrong.

And then you top if off with tropes like "however they identify", as if to say that being transgender is nothing more than some kind of delusion.

Yes, you are a transphobe. Just because you don't call us the T-slur, or freaks, or some other disgusting epithet, you're still a transphobe because you define us according to your ideas, not reality.
