How to be a racist

In the aftermath of the Baltimore riots and the charging of 6 police officers for the death of Freddie Gray, one thing I have read in a few places is "...but 3 of the cops are black". The implication is that being black means one cannot be racist. I decided to look up racism on Merriam Webster (great site to remember...you don't even have to bookmark it...it's m-w.com):

Missing in that definition is the race of the racist. So why do people think minorities can't be racist? Racism is is about how you treat others. If you think a group of people are inferior simply because of their race, you are a racist. It's really that simple. Reminds me of the Dave Chappelle skit featuring the blind white supremacist:

So what does this have to do with the Baltimore cops? Not much...just tired of people assuming this incident isn't about race because 3 of the accused officers are black. Or that the special prosecutor's report and actions will be accepted just because she's black.
