I've never really thought about that sort of issue. Yeah, you always hear about black transwomen getting targeted above other races, but I've never even thought about how people might see someone differently as a black male vs a black female.
While it does suck that this is something you'll have to adjust to, keep in mind that most black transmen/women usually end up passing very well pre-hormones! So I guess count your blessings, and of course, stay alert and stay safe!
