I think the hard-distinction that trans people have as putting themselves in little boxes like 'feminine' and 'masculine' are kind of harming the whole idea.
Having tea parties isn't girly. Playing with dolls isn't girly. Wearing pants isn't masculine. Playing in the dirt as a kid isn't masculine. They're just kid things. There's too much emphasis on what's boy or girl like, and people are convinced they're "a girl" because...they like pink? They like tea parties? They like the clothes that girls wear? You can still be a guy and like those things, those aren't "girl things", they're just things. I hate this idea that everything has to fall into one of those two categories, and if you like something from the 'other side' you're trans.
It's perfectly acceptable to like/do things that the other sex does, without BEING that sex.
