I'm certainly willing to engage with you if you make a point that I disagree with - read this thread and my comments in it for proof of that - but that "phrase I don't like" is a racial slur, full stop, and the idea that you "learned it from a black man" fully excuses it's use in every conversation, in every venue and at any time you like going forward is, well, wrong in a way that I don't think you'd ever be able to accept.
Consider editing your initial comment, and reflect on the idea that butting into a thread with a throwaway racial slur is perhaps not the way to get people to engage with you.
