How do Larouche people respond to Witzsche's "Enabling the Inevitable"?

[+] Rolf Witzsche makes a stunningly reasonable case against NAWAPA in this article. How do the Larouche people respond to it? I've already had one Larouche person hang up on me (slamming the phone) after I tried to talk to her about Rolf's ideas. This is the first time I've seen evidence that the Larouche people are being blinded somehow... which is astounding to me given the line of history and economics I've been reading on the Larouche site for 10 years. Is Rolf getting any reaonable feedback from Larouche people or do they slam the phone down on him too?
