> nearly everyone in the USSR was a farmer, so not proletariat and not communist
This statement has a number of flaws.
> nearly everyone in the USSR was a farmer
True during the early years, but after WW2 changed rapidly (in line with the West). [1] shows rural population percentage dropped from 67% in 1939 to 56% in 1956, and it rapidly decreased after that. [2] is female specific but by 1975 under 1/3 were working in agriculture.
In addition, everyone other than the actual owner of the land was considered "The Agricultural Proletariat". Engels wrote [3] about this in 1845 well before the establishment of the Soviet Union.
> so not proletariat
As seen above, this doesn't follow especially after the establishment of collective farming where everyone were considered workers.
