Outstanding documentary and I mean no disrespect but it is amazing that by his own words he was a progressive liberal and would not understand that his own ideas were part of his downfall. Liberalism leads to socialism which leads to communism.
I hate to nitpick, but...Liberalism is communism, and the goal of communism is socialism. But, your statement still has its merits for the effort.
Warning stickers on every product known to man telling people not to be stupid. However that takes natural selection out of the game. No warning stickers and people doing stupid stuff would be less likely to pollute the gene pool.
