I now challenge you to prove (e.g.to Formaldehyde) that racism does not exist in modern US either. You can use all the same arguments. After all, official policies of US are very explicitly anti-racist and much effort is being put into affirmative action. Also, black POTUS.
So you don't understand how structural racism works.
Were non-Russian nationalities routinely demonized in Soviet press and media? Were they left at the bottom of the social strata and not helped to have the same opportunities as any other nationality? Were there regularly attempts by large segments of society to exclude them or to institute laws which were unfairly biased against them? Were any ethnic minorities denied the ability to live or work in any location or job based on that ethnicity, while others were allowed? Were they constantly made to feel that they were, at any point, not fully equal to the other ethnicities in the Union? Were they even denied control over their own culture and affairs?
Of course not.
To give another example: after the serfs were freed in 1861, were they then equal? Or did they face serious impediments to their advancement, such as continuing legal bias against them and people in their position, prejudice and exclusion by other parts of society, and neglect to their needs and squalor by that society? The peasantry obviously isn't a race, but imagine that all the peasants were of one race: that's the situation of Blacks in the United States, except worse, because then after all the above, Jim Crow and the KKK came along.
The Soviets, on the other hand, actively worked to both reverse Great Russian chauvinism and the Russo-centric economy, giving all ethnicities power over their own affairs, and the less-developed ones, who suffered advancement at the expense of Great Russians, favorable placement in universities, particularly trade schools, and the non-Russian republics, like the Central Asian ones, extensive industrial investment and modernization. Hell, even the Baltic states, directly after incorporation, were fitted into the present Five-Year Plan, and immediately all became Soviet citizens.
Read that again slowly for yourself
Then imagine being sent to stay within 20 miles of Kwethluk, Alaska and told that you never lost an ounce of opportunity.
Show me an ethnicity for whom that was the fate. Not individuals, but groups
as ethnic groups.
And by the way, nearly all ethnic deportees returned home again. You're from Estonia. Most of the Estonians deported in 1940 simply turned around when the train arrived wherever it was going, and went back home again.
Some had to wait until later, like the Chechens, but their situation was unique, as they actively collaborated with the German invaders.
