Ali G had an excuse when it was only in Britain, when Tim Westwood, a white middle class son of a bishop, was on national radio sounding like a black Londoner hip hop DJ.
That excuse evaporated when the character was taken to the US. Ali G may have started off as a parody of Tim Westwood, but without that cultural context became racist.
And if you have an issue with cultural appropriation, do not listen to or watch Tim Westwood. He was tolerated in the 80s and 90s because he was one of the few rap/hip hop shows on the radio but he’s still doing the same thing now.
