Very good point, but there's also, seemingly, a widespread perception that those killed by government policy are not really murdered the way those killed in the holocaust were. Start 100 million and you can always blame it on "the capitalists" who "were too greedy", even if your country was a communist one.

Never seems to have the impact of killing 10 million in gas chambers, which is why it is the more popular method than gas chambers for the modern mass murderer.
