One thing, the USSR was not an atheist state.
The people of Russia were still very religious even after the Bolshevik revolution. And, every one of the satellite provinces taken into the USSR, such as Georgia, Belarus, Poland, East Germany, etc... were pretty much the opposite of being atheistic.
And, your statement about alcoholism I venture to guess, has no demonstrable samples. The Russians, Polish, etc... drink vodka like the Italians and French drink wine. It is done with food and is part of their culture. That is like saying all Italians are alcoholics. An alcoholic isn't someone that drinks every night at dinner. An alcoholic will actually alter their life to get a drink and drink during the work day, etc...
But, anectdotally, I would probably drink a lot living in the USSR as well, especially the last couple of decades. Hell, just thinking about our Congress or watching a clip of FOX News makes me go to the sideboard and poor a scotch now.
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot."--Mark Twain
