He's pulling the "people have no sense of humor" shit.
See though, when you make race jokes it's up to the race you're talking about to decide if you're being offensive or funny. And we agree he's being racist to us. When a conservative comedian who hates brown people makes these "jokes", we know they're not really jokes
I try not to give negative reviews. I stick with either a positive for something truly outstanding or nothing at all (my default). But an unsafe driver gets a negative review because I want to protect other passengers. Similarly, I'd ding a driver who had political or religious garbage playing. They should create a neutral environment.
