At least on Soybooru, it's because being Aryan is seen as good, and Aryans are white, so being white is seen as good. Due to this, every single shitskin from every 3rd world shitskin shithole wants to be white.
I don't understand the purpose of this message. I am not trans, nor do I want to be a woman. I have never said any of these things. Have you posted on the wrong person's profile?
The booru is not just a bit bigger. It's a lot bigger. While a lot of users use it due to it's connection with the sharty, just as much use it for soyjaks only, and just as much use it as their main soysphere site.
