My initial comment was backed by two non Black people. So what does the person do when confronted with three people saying the same thing and only one of them is Black?
Can you say attack and disrespect the Black person? Thought you could.
One of the things that pisses off me and other POC's in interactions with non-POC's is this tendency you have when you are confronted with information that doesn't fit your world view, unless it comes from a fellow white person, you huffily attack the POC messenger. That phenomenon exists whether the white person is a conservative, liberal or independent.

Point is, it's our history, and many of us were raised and immersed in it. So it would stand to reason that we can quickly spot any incorrect information being disseminated and will seek to correct it.
But don't get an attitude because we did.
