I am male but not a man.

"Saying trans-womxyn are male is the core root of transphobia" – there, do I win?

The differences between a trans-woman & a man are only in the imagination of the individual. What's the difference between trans-womxyn who say they are women & trans-womxyn who say they are men? Ideology is the only difference. Meanwhile there isn't any overlap between trans-womxyn & women, other than everything that men & women have in common.

After a female infant, that was brought up by wolves, identifies as a wolf & has no concept of gender, finally grows up, she is a woman, not a wolf, because 'woman' is just the word for a human who is an adult & female.

You can't prove that trans-womxyn are women, so you say it's transphobic to say otherwise, but you also can't prove that that's transphobic so why on earth should I believe two impossible things with nothing to back either up (other than the vague "but it's the core root though")?

The reason the other side isn't saying that it's transphobic to call trans-womxyn women is because they have evidence on their side. It's from your lack of evidence that you have to lean so heavily on the "transphobia!" crutch.
