I guess it’s understandable that some people can be confused by gender non-conformity, but when the confusion rises to the level of hostility or opposition, I think we need to step back and examine what we’re doing more closely.
It’s hardly shocking that a trans man might want to wear his hair long and dress in glittery things. Plenty of cis men do exactly the same thing. Many of them are my friends. ;-)
Seriously, as a gay man, I’ve often been surrounded by cis men who reveled in certain feminine mannerisms or modes of dress. For lots of different, personal reasons.
Why should a trans man be any different? More importantly perhaps, why should anyone try to force them to be?
