Well, formally, you are right that Crimea is 90% Russian ethnically, but what about price?

- In 1940s, USSR totally resettled all Crimean Tatars to Siberia, and only in 90s they got permission to return home. For comparison, imagine US will resettle all people from Florida to Alaska - you will not name this genocide?

And yes, resettling of peoples, was typical for USSR, and Russia was main power in USSR, even when prime ministers was from other parts of Union, so demography policy was pro-Russia. For example, up to 1990s, Russia constantly resettle Russians to Eastern Ukrainian regions, and same way, now Kazakhstan, and other Asian exUSSR counties have large share of ethnically Russian population.
