Everybody who hasn't been brainwashed by this nonsense (or brainwashed by the old stupid ideas about gender) is "agender." Again, "gender," as you use the word, is meaningless. What experiences does "man" involve in your opinion? I presume you don't even believe "man" has anything to do with being male. So what is it?

As far as I understand, and I'm talking about your framing, not mine, it's an idea in whoever "identifies" as a man's head. But, of course, there's no way in the universe that two people will have the same idea. If I asked every single one of my male friends what it meant to be a man, well, actually, most of them wouldn't know how to answer (I've already asked a few of them). But if I pressed them, they'd each give a different answer.

Does this mean that none of them are men? Because they don't have the same "man feeling"? Or that they're all men, but the "feeling" that makes them men is different for each of them, meaning that there isn't a specific feeling that makes somebody a man? Which again, means the word has no meaning.

How specific do we need to get about our behaviour before we realise this is all a bunch of self-absorbed, incoherent nonsense? Or to be more charitable, as I said earlier, simply a synonym for a personality.
