I don’t know whether she’s doing it intentionally, but she’s whitewashing the part about religion in the USSR. According to Wikipedia:

After the October Revolution … the communists aimed to break the power of all religious institutions and eventually replace religious belief with atheism. As part of the campaign, churches and other places of worship were systematically destroyed, and there was a “government-sponsored program of conversion to atheism” conducted by communists. … The communist government targeted religions based on state interests, and while most organised religions were never outlawed, religious property was confiscated, believers were harassed, and religion was ridiculed while atheism was propagated in schools. In 1925, the government founded the League of Militant Atheists to intensify the persecution.
