Or this lovely infracted gem:you have zero sympathy for autistic people?
What on earth do you mean by that?
Tsu: Because I have my own beliefs, okay? And some part of me believes they were as lenient as they were with this guy because the kid was autistic and it's not seen as any loss.
Tsu: Don't point fingers at me for coming up with this belief, autistic people are widely accepted as a burden/nuisance to a progressive society and born from bad genes.
I merely have no sympathy for his death is all, I just don't condone this driver's antics. Don't jump to conclusions like I want anyone to die or anything, all it is is no sympathy or sentiments for anyone with autism, or wanting to do anything with them personally.
