My personal experience with the few I've known is they tend to be overly difficult to get along with and defensive, to the point of being hostile. Part of what makes them difficult is, again it's the few I've known, they tend to aspire to male privilege but also demand to be deferred to in ways that a woman typically would. Unfair.
Also, I can smell vagina, on some level we probably all can smell vagina. It's not an odor I enjoy at all anymore and it keeps me from taking a trans male seriously as being a man.
As for their personal journey, I think it must be a hard row to hoe, especially for vulnerable young individuals, and I wish them well. It's not for me though as I've already had a few difficult experiences dealing with them. Now a male to female, that's a whole other story. I'm good with that.
