Stalin and Mao were both atheists who sought to stamp out religion. How many millions died because they chose to believe?

Within just weeks of the October revolution, the People’s Commissariat for Enlightenment was established to remove all references to religion from school curriculums. In the years that followed, churches and monasteries were destroyed or turned into public toilets. Their land and property was appropriated. Thousands of bishops, monks and clergy were systematically murdered by the security services. Specialist propaganda units were formed, like the League of the Godless. Christian intellectuals were rounded up and sent to camps.
The Soviets had originally believed that when the church had been deprived of its power, religion would quickly wither away. When this did not happen, they redoubled their efforts. In Stalin’s purges of 1936 and 1937 tens of thousands of clergy were rounded up and shot. Under Khrushchev it became illegal to teach religion to your own children. From 1917 to the perestroika period of the 1980s, the more religion persisted, the more the Soviets would seek new and inventive ways to eradicate it. Today the Russian Orthodox churches are packed full. Once the grip of oppression had been released, the faithful returned to church in their millions.
The Soviet experiment manifestly failed.
Stalinism and Maoism were not just about being anti religion, it was about imposing a state enforced conformity. China these days gave up suppressing religion and has attempted to regulate it in same ways. In pre revolution Russia the church was an arm of the aristocracy used to suppress the lower classes. You could buy forgiveness for killing someone in the lower class. Russia was brutal on the lower classes.
It is no mystery why the revolution turned against religion. When the Soviet Union collapsed the Eastern Christian Church moved quickly to regain power and suppress other Christians. Billy Gram had a tough time getting permission to hold one of his rallies.
You can try to equate atheism with the worse of religion, but it is not so. In Russia, China, and North Korea were complex historical, ethnic, racial, and political issue of which religion was a part.
The Cold War was about polecat and economic systems, not religion. Historically religion has been the rott caie of a majority of conflicts. For centuries Christian Europe vs the Ottoman Empire which was Muslim. A few battles gouing the other way and Europe may have gone Muslim.
Muslim vs Hindu in India followed by today Muslim Pakistan vs India which is in a running low level shooting war over Kashmir.
I expect most atheists in general accept religion under free expression and right of assembly, as long as religion does not exert coercion and demonizing atheism and does not impose faith through government. What atheists in the USA oppose is Chirality imposing a morality derived form an ancient disjointed text of unknown authors through laws and government.
We do not have Stalin or Mao. We have many Christians who claim to know what a god wants and then tries to impose it on us non believers. Just like the enforced ideology and morality of Stain and Mao.
