Well, it depends how much you think the actions of Stalin, Mao, current Chinese regime, Burma guys, etc. is motivated by the religion eradication factor, rather than the power/land/money things, perhaps.|
I really don't believe a single factor is enough to make anyone but the seriously unbalanced commit murder. One thing militant atheism has protecting it from this sort of deadly motive mix at the moment is the lack of a big, organised cohesive 'doctrine', but there are definitely signs that is changing, so I hope you're right, else I might end up hanging off a lamppost one day =)
