Welcome to Tumblr.
I know people sometimes feel like they're of the wrong sex, but it's gotten to the point where it's the cool thing to be.
You can't know for a fact whether or not someone is truly trans - so it's best to act as though they are. If you did the opposite and treated everyone like they're "fakers trying to be cool", then you risk severely hurting someone.
