That is not a pic of a 21 yo kid.
If the manifesto turns out to be real there was a spot in it where he says he is against mixing ethnicities because it confuses the children or something ...Looking at his pic I wonder if that’s what really eats at him because even though he’s pale from being on the internet al, the time, he’s a mix. Shoot up people in a tantrum over being confused about what he is?
