Of course personality isn't meaningless. What's meaningless is trying to name it. What is the word that describes your personality? And would you expect it to be the same word as anybody else's? What is the point in every human on Earth inventing a word that describes our personality? And then getting mad if everybody doesn't validate and use our word. And, of course, stay up to date when the word inevitably changes. This is the self-absorbed incoherence I was referring to.

There is a proper definition of man. Just not in the confused circles you move in. It's the same definition that we've been using since the birth of the English language. We see this very clearly when issues get important enough. Very few people were struggling to define "woman" when Roe vs Wade was being overturned, for example. Ask 99% of people who don't spend their lives on Twitter and Tumblr and they all know what a man is. And most of them will be evolved enough that they don't tie their definition to behaviour but simply biology.

Again, it's amazing to me how you don't realise how bizarre and regressive the things you're saying sound to everybody who isn't brainwashed. The thing most men have in common is that they have a penis. That's it. For everything else, you have to rely on the very same stereotypes we've been trying to escape. It's your ideology that insists that if an adult human male likes dresses or liked playing with dolls growing up or is simply a bit effeminate, they're a woman.

You keep ignoring this simple, obvious problem. That your ideology relies on the same stereotypes the Christian conservatives did in the 1950s. Stop ignoring it and actually think about it.
