You are a liar.
Everyone is a racist.
I'm a racist, Jakko's a racist, you're a racist.
It's hardwired into our minds. Don't try to deny it.
If you're saying that you don't belittle or ridicule white folks, that means you're trying hard not to be a racist, which conversely makes you a racist because you're thinking about not being racist to them.
The fact that you're arguing that white people are racist also makes you yourself a racist. Think of the other side of the coin, were the minorities the white people oppressed unbiased saints? No. They hated the white people just as much and the white people hated them.
