I've read it. What you said is this "During Stalin, it was the general policy to suppress national languages.". This just isn't the case, especially given the duration and the complexity (and contradictions) of policies in use during his tenure. There was certainly Russification. It's hard to point at any period where there was a straightforward "general policy to suppress national languages".
> "During Stalin, it was the general policy to suppress national languages."
It existed in general, but it was especially intense from 1930s until early 1950s. So during Stalin in particular a lot of damage was caused. It's not hard to point out at all.
Even that reference does not say anything close to "During Stalin, it was the general policy to suppress national languages." There was no such general policy, the thing you link talks about the tension between the desire for centralized (typically Russian) control and the Marxist ideological demands of 'internationalism'.
There was no "tension". Formal internationalism was quite effectively replaced with persecution of ethnic and religious minorities, including suppression of languages and education. Internationalists were some groups like Makhno's anarchists. Stalin was the complete opposite.
But I think I'm wasting my time here. If you want to deny historic facts, do it elsewhere.
