hi! the Soviet Union was formed after slavery in the USA was abolished, but you may be interested in these posts, which touch on their opinion of racial segregation & racism in the USA

• Did the Soviet Union have a "bite-sized" refutation of Capitalism?

• When segregation was legal in the US, how were prominent black people from Africa (or other non-North American countries) treated on visits to the States?

• Did fear of Communism play a significant role in the granting of civil rights to American blacks?

• How did other nations, particularly the Soviet Union, react to the Civil Rights movement of the 1960s in the United States?

• Escaping to communism

• During the Cold War, did the Soviets have their own James Bond character in the media? A hero who fought the capitalist pigs of the West for the good of Mother Russia. - a couple of comments

Plus, I remember a thread that included someone mentioning this animated short, Mr Twister (part 1, part 2), but can't find it. If anyone can remember the post title or find the link, please reply here. Thanks!
