Aromantic : uninterest in romantic relationship.
Asexual : uninterest in sexual relationship.
You see, I see more the LGBTQ+ as a description of your relationship with others, but also with yourself.
All of those case are for a tiny minority, although it's not uncommon to stumble on it one day or another.
It always existed, but I think the internet amplified the visibility of those people, and also those big companies who decided to make money out of it...
But really, apart from the syndrome or the exiled they are totally normal.
And if you wanna talk about trans, honestly who cares how they dress ? And my personal take is that they wouldn't have to change their gender if some people cared so much about the separation of boys and girls.
