To follow on from my previous comments about the Left being unable to indentify what a woman is, if that is the case, how can they identify what a trans woman is? You have the same problem. Also, if they say a trans woman is a woman, why do they have the "trans" in there? If the argument is that it is because it is a man who identifies as a woman, then they are saying they are both man and woman at the same time. If they say it is because they transitioned, then what if they were born male but always considered themselves female? Where is the transition? There is none.
The whole thing is nonsense!
Edit: Further thought...if you cannot identify what a woman is, then you cannot identify what a man is. If you cannot identify what either is, then how do you know if someone has changed from one to another? How does someone who claims they are transgender know they are in fact transgender, because they do not know what the starting point is (male) or what the finishing point is (female). Both are undefined.
