Guys. Sex has to do with your body, your DNA, whether you got that Y chromosome or not. Gender is what you identify as, what you are mentally. For example, If you think, act, talk, or wish to be "feminine" (What I mean by that is not the stereotypical gender roles, but more physical things like speech or mannerisms.) Then your gender is female. But if you got that Y chromosome, then your sex is male. Get it? You guys are confusing Gender-Roles with these things and it is making things confusing.
Anyway Actually On Topic. Things like this exist because people who don't understand things, and don't wish to understand, like to ridicule, and make fun of those things. Whoever created this Youtube Channel assumed it was natural to hate on us and wished to be youtube famous by exploiting that. obviously it was not a good idea.
Guys don't try to White-Knight it. They aren't worth the trouble.
