I was called a black c*nt

I was performing a stand-up comedy set in a local pub. A drunk white guy heckled me early on in the set. Based on his slurred comments it appeared to be due to the colour of my skin. After the set he came up to me and apologised – “affectionately” saying “come here, you black c*nt” and giving me a hug. I didn’t know how to respond. I just accepted it because, in my mind at the time, at least he wasn’t being aggressive towards me.
