I don't defend trans people or argue the validity of labels like pansexual because all of it is associated with lying fatarses.  Tumblr's misuse of "transgender" frustrates me to no end.  If you don't actually have dysphoria, if you're just a girl who likes to wear basketball shirts, you're not a "demiboy," you're not transgender at all.  That's not my opinion, that's the medical definition.  At best, it discredits actual transgender people.  At worst, it feeds high-grade ammunition to politically influential people who want to block access to hormones, surgery, etc. when transitioning has been shown to make a massive difference in suicide rates.
