In my post analyzing the "The Story of Stuff", an environmentalist-Marxist propaganda film aimed at grade schoolers, I linked to a youtube video that performs a line by line critique of the entire film (HT: Harold). He now has a second part posted as well. I highly recommend this devastating critique.
Incidentally, I noticed that the producer of the critique has his own site at HowTheWorldWorks. He engages in several video debates which he has posted and I highly recommend them. Here is one that I enjoyed. In this post, note the long list of anti-human environmentalist quotes he offers to refute his opponents sarcastic claim that environmentalist are really not the "misanthropic caricature" that anti-environmentalists charge them to be.
As an aside - another interesting aspect to this video is the calm, thorough logic of the producer in presenting his arguments as opposed to the hysterically illogical diatribe of his leftist opponent (which includes the offering of a middle finger at one point!). This phenomena is not a coincidence, a fact which I analyzed in some philosophical detail in this post, also here, and here.
