Speaking as a 'cac' , I don't find the term racially offensive per say, just a bit in poor taste. It's no skin off my nose though, like someone else said, on the internet people take jabs/ make fun of each other over basically anything, why should race be any different?
As someone who has never acted in an even remotely racist manner though(not just in regards to blacks but every other race), I find the 'white supremacy' bit somewhat curious. Specifically the venting of frustration against
all 'cacs'. Now I'm not gonna debate the fact that there may or may not be a 'white supremacy' conspiracy going on at high levels, because I have neither the desire nor the information for such a debate, but never think that this conspiracy extends to every cac. The average cac, which I happen to be, worries about money, sex, friendship, entertainment, health and all the other usual stuff just like any other motherfukker. We don't concern ourselves with keeping the 'white man' on top or whatever. I care about individuals, not entire races. Just myself and the few handfulls of people that are important to me. I treat everyone else the exact same way.
