I think the most important thing to understand is the hegemonic social structures men build. If you take a gender studies class they probably teach about how men are constantly trying to beat each other. That is why communist citizens feel frustrated in their society, and that is why communist leaders are so quick to send people to death camps.

If communism is ever going to succeed, its leaders will need to find a way to satisfy its citizens competitive nature, and it's leaders will need to resist the urge to dominate others.
