Hear me out. I've seen quite a few videos on people who believe they were "meant to be black" or "deep inside, they're a small child". Now obviously these could be faked for attention, and if that's the case, they certainly succeeded. But for the moment, let's assume all these claims are real issues that they're dealing with.
People who come out as transgender are usually seen as courageous, groundbreaking, etc. They have certain rights, they're a significant part of the LGBT community, and above all, if someone wants to dress as, act like, and even transition to the opposite gender, in this day and age not many people are going to stop them.
On the other hand, these transage, transracial, trans-etc people tend to be seen as weird, and many people commenting on the videos in which they were featured said something along the lines of "they need mental help". No one appeared to be encouraging their behavior. No one even said things like, "It's their body and their life, who cares what they do with it?" or "If they want to act like this, go ahead, fine by me." Pretty much everyone had negative reactions.
So the question is, assuming these are real mental issues these people are suffering from, why are so many transgender people not being looked at the same way? Why do we look upon some people with disdain while we applaud others with very similar claims for being so brave?
