In case of USSR the people were choosing sides of the civil war and fighting voluntarily - a more serious commitment than simply casting a ballot.
I am not a historian, but I think the society turned this way, in a sense. It's not like some external force coerced them, when everyone was against it.
Hashek is an example. He was not forcefully conscripted, it was his choice.
I've just recently listened to Kerensky's interview (the chairman of the Provisional Government that was ousted by the October Revolution in 1917). He was unable to gather any forces, no-one defended him.
