I picked up on that, too. I'm not sure too many will get it though, it's a little esoteric.
Comparing Beck's materialism with that of Marx, Engels and Alinsky is absurd.
Esoteric, but there is a huge difference.
Now, that's a good point others have made as well. It's not like pregnancy, you can be a little materialistic or even a lot materialistic without buying in to a stupid theory of historical analysis. Maybe Farah thinks you have to poke people in the eye with a dialectic stick to make your point. I do think that taking the materialistic worldview as a given hurts the conservative side of many an argument, particularly when that view is inadequate so often.
