YES.  Tumblr gets mad when you quote medical science about neural circuitry and tell them that, by defintion, if you don't have dysphoria you're not transgender.  For example, being female and wearing baggy basketball shirts does not make you transgender. The term for demiboys and other made-up obeast sexualities is "tucute."  Actual trans people are known as "truscum."  Tumblr's view of sexuality, whether it relates to gender or ugliness, is very similar to that of anti-gay conversion therapy--that attraction can be changed, that you can choose what you are.  Scientifically speaking, it's bullshit.  You can't change genetic predispositions or the amount of testosterone and estrogen your brain got in the prenatal environment.
