"Is there a way to become racist?" Why would you want this? It is an unnatural state of being for any human being. Humans have never wanted to be "racist" or disliked other groups as a way of surviving and to keeping out hostile/subversive elements within their own groups. Notice how right it feels when everyone becomes non-racist,  when it does not even need to be forced upon them, because the hostile behavior and subversion of the racist heritage disappears. Racism is just another one of those elements used to attack tolerance and  multiculturalism. You should embrace what our common ancestors learned long ago that helped them survive and thrive to where we are today. Trying to be the opposite of tolerant and non-racist is self-destructive to yourself and society as a whole.
