Can People of Colour be Racist?

I'm posting this quote because I get super frustrated when folks derail many of my arguments about racism and claim that "people of colour can be racist too," without even listening to what I was really saying. I.e. "I'm not going to listen to stuff about white privilege etc., because everyone is different and we're all horizontally racist... and reverse racism...blah blah blah."

Here's a great quote from Beverly Daniel Tatum's, "Defining Racism: 'Can We Talk?'"

"Of course, people of any racial group can hold hateful attitudes and behave in racially discriminatory and bigoted ways. We can all cite examples of horrible hate crimes which have been perpetuated by people of color as well as Whites. Hateful behavior is hateful behavior no matter who does it. But when I am asked, “Can people of color be racist?” I reply, “The answer depends on your definition of racism.” If one defines racism as racial prejudice, the answer is yes. However, if one defines racism as a system of advantage based on race, the answer is no. People of color are not racist because they do not systemically benefit from racism. And equally important, there is no systematic cultural and institutional support or sanction for racial bigotry of people of color. In my view, reserving the term racist only for behaviors committed by Whites in the context of a White-dominated society is a way of acknowledging an ever-present power differential afforded Whites by the culture and institutions that make up the system of advantage and continue to reinforce notions of White superiority."
