There are certain psychological traits of mine - certain feelings that I have - which I gather are less common in men. I fancy men. I'd rather collaborate than compete, and I just don't give a toss about football. I don't like taking unnecessary risks with my physical safety. I always think people are going to find out I'm crap at everything. I think my son is the most beautiful baby ever born.
But...none of these traits appear to be particularly prevalent among trans women. They aren't peculiar to women, either, or universal among them. I've never thought of lesbians as quasi-men. Not the ones I know, anyway.
Like 100% of the rest of the world's population, I have no way of knowing whether the way I feel at any given moment would be different if I were of the opposite sex - except at times when the way I feel is directly related to my reproductive function. I felt sick when I was eight weeks pregnant. I felt blooming and happy when I was five months pregnant. I felt a bit shit when I was two weeks postpartum and had had no sleep and was dealing with lochia and stitches and postnatal depression. I know, logically, that these feelings are peculiar to women.. but not all women have experienced them, and there are other feelings peculiar to women which I have never experienced (I don't get period pains, for example).
There is no criterion or set of criteria which adequately defines the group "woman" in terms of feelings. If there were, none of us would know what they are, because none of us have ever been both a man and a woman, and so we have no way of comparing the two states.
If a man wants to "live as a woman" that's fine by me -not like I get to decide how other people ought to live. But that doesn't mean he is one.
