You aren't a frequent poster and there's no evidence of prior bad outbursts like this so I'm going to give you do benefit of the doubt, remove the infraction point (for now), but also try and explain some things here so that hopefully this can be a teachable moment.
When you type "All black and brown kids aren't on the take, Sir," you are necessarily implying some of them are. And, factually, that's probably true. But, then again, aren't some white kids also on the take, too (just on our team, we all know TVD is driving around in a pretty nice 7 series he didn't pay a dime for)? So if we can agree that's true, why mention skin color at all? Why not just say, "All kids aren't on the take, Sir"?
Additionally, it's somewhat troubling in the context of the comment you were responding to, which was alluding to poverty (i.e., "You sound like a man that’s never been evicted or hungry."). Most likely not with ill will, you seemed to (probably subconsciously) equate poverty (via eviction and hunger) with black and brown kids. But plenty of white kids live in poverty, too. So again, why mention skin color at all? Why not (more precisely and racially neutral) say, "All poor kids aren't on the take, Sir"?
Just some food for thought.
