"Viking" is not an ethnicity. It was more of a job title.

I am seriously disturbed by the fact how fast these kind of discussions degrade into fascist skull measurement exercises.
The whole trend of invoking the matters of Russian racial purity feels dangerously close to western 19-20 century rhetorics on people of Africa or Jews. Russians are Tatars, who are in turn pagans? What???? Russians comprise of multiple ethnicities (yes, including Tatars). And Tatars are largely muslims, not "pagans", don't be a racist!
In real life the evil "Jail of Nations" not only does not forbid you to speak the native language, but actually teaches them and even allows their use in legal documents, unlike the good "Russia now Ukraine" which actually restricts the use of native language of 1/3 of the population, and it's not just the legal documents, it's also press and spoken communication in public places (i.e. if you are a shop owner, you can get fined for speaking Russian). How does that fit into your racial theories?
Also, you'd probably want to lookup the word "colony". I get where this narrative of "colonial Russia" is coming from, but you'd have to completely uninvent the meaning of the word for it to make sense. Colonies are foreign (typically overseas) territories with a separate administration. There is a huge formal difference between colonies and incorporated territories. Russia didn't have any real colonies for at least 1.5 of a century.
You can't just invent new random meanings for words just so that you can use their connotations in your propaganda - what you are doing is purely Orwellian newspeak.
