I know what butch is. Butches are not beginner FTMs, except that sometimes they are, but it’s not a continuum except when it is. Butch is not a trans identity unless the butch in questions says it is, in which case it is, unless the tranny in question says it isn’t, in which case it’s not. There is no such thing as butch flight, no matter what the femmes or elders say, unless saying that invalidates the opinion of femmes in a sexist fashion or the opinions of elders in an ageist fashion. Or if they’re right. But they are not, because butch and transgender are the same thing with different names, except that butch is not a trans identity, unless it is; see above.
