I worked over five years in an overseas place with 2500 men onsite. Total of 15- 20 whites. It was great. Arabs, Africans, South Asians, East Asians and a few white people. I was one of the whites.

Back in London I was soon cautioned in the nicest possible way for saying things people might think were racist. I was also advised that working in repressive places meant I was participating in the repression. London is infested with self-censorship by white people.
