"Limey" I haven't heard that term in a long time. Over the years I worked for several Brit oil companies overseas. My Brit coworkers had several names for Americans too. None of which bothered me at all. We all got along just fine.
This race BS gets thrown around a lot in this country. But compared to many of the countries where I worked, where there was true racism, the US is the least racist country in the world.
It used to be YANKS but these days its usually MERKINS Canucks, and I wont repeat what we oftyen call certain European nations
Wanna see racism go to Nigeria, Zimbabwe or South Africa and see how whites are treated, or in many countries how Arabic Africans treat Black Africans and vice versa. Go to Spain and see how the Spanish treat the Catalans, of south america where the Hispanic community treat the indiginous peoples.
