Guys, guys. It's not racist at all to try to work casual references to dire anti-black racial slurs into your show about cars if you just make sure to never hire any black people to work on filming or editing it. It's just like how multiplying two negative numbers gives you back a positive one--make sure you don't do an odd number of grossly racist things on set and you're fine.
Has the production team of Top Gear been known to "never hire any black people to work on filming or editing". Can you elaborate on this accusation and tell me where you sourced it from?
