I've noticed that a lot of AFAB so-called enbies make zero effort to distance themselves from womanhood/femininity. They just put "they/them" in their bios and call it a day. Despite claiming to totally not be women, they continue to dress and act like them and many even whine about issues that only a woman would ever care about (there was one on my feed complaining about violence against women in horror movies, for example). I've seen they/them e-thots who literally flash their tits and pussy online and yet still claim to be heckin cute and valid enbies.
I know understand why they do this. It's a way to be "not like the other girls" without actually committing to whole "man" thing. There are very few "FTMs" who seem to actually want to be men, and for good reason - men, especially men who are not conventionally attractive (aka every actual FTM ever) have it worse in our society. I was a stealth FTM for half a decade before detransitioning, I would know. I was treated much worse as a babyfaced manlet then I ever did as an average looking woman. It doesn't matter what pronouns you put in your bio, in the real world, if you look like a woman, people will treat you like one.
