No, a comment can be racist, it matters not who the speaker is.<quoted text>Truth is not racist, and in order for my comments to be labeled as racist, I would need to be a minority, which I am not. Try again!
Saying, "white people is doing all the killing!" is racist. One, it's not true, and two, it assigns race as a causality.
I can say "a black guy I know likes watermelon". Not racist.
Saying "all the black folk eating up watermelon!" Racist. See the difference?
Now, you could had said the mass shooter in Connecticut was white. Not racist. But saying "white people are doing all the killing!" is most certainly racist.
Funny how you then had to go back and add the caveat that the deadliest shooting rampage on US soil was perpetrated by an Asian, destroying your entire race-based argument in the process.
