I am not a racist but i am prejudiced.
I believe everyone is prejudice, it makes it easier for us to define people or draw a conclusion on someone. Whereas racism is all about acting on those prejudices.
Some people say that to be racist you have to be the one with the power, this leads some to say that minorities cannot be racist, interesting and debateable.
I can see what BTS means that race is a social construct, in turn racism is a social construct. It doesn't mean however that it does not exist.
Ultimately it should be realised, "that there is no race except the human race."
