But really, you can't.
It's sort of like nuclear fall out, you don't just get a pass just because you feel bad.
We live in a society built on bones and blood. Its sort of like when those kayakers got made fun of for protesting an oil company while using petroleum products. There is no other alternative.
Black, Asians, the multitude of others are all capable of engaging in, and incapable of escaping racism. Just like white people. It's just that, through massive apathy and an unwillingness to acknowledge this inherent facet of our society, it's hard to admit that we're all racist as fuck.
Just because you don't want to exterminate people doesn't mean you're not racist.
You can always strive to not be a piece of shit though, as we all must.
