I don't get it

So I'm really wondering why some trans guys when they get on T and have been on it for long enough to always pass, just suddenly start acting like they're better then you because you haven't transitioned as far medically as they have? Why put me down because my face is round and I got small shoulders? Yeah I'm 5"2' doesn't make me any less of a man... Like we all grew up the wrong gender, we're going through the same. I don't get it?
