Do you believe that's a good reason to continually turn a blind eye when someone constantly promotes blatant lies? If anything, the absolute absurdity of Tim's claims make it look like tinfoil hat nonsense and therefore make a mockery of what should be a serious issue.
FYI a year before the GFC spike,
corn prices ranged between $2.90 and $4 per bushel (November 2006 to October 2007). US
bioethanol production (<90% from corn) more than tripled between 2006 and 2015 (4,884 million gallons to 14,807 million gallons), and in the comparable period November 2015 to October 2016 corn prices ranged from $3.20 to $4.40. That's a 10% increase. On the other hand, it's almost a 50%
decrease from the 2011-2013 prices, despite an 11% increase in production from 2012 to 2015. Bioethanol demand must inevitably have
some impact on food prices, but "no one can deny" that those impacts are A) impossible to precisely quantify but B) obviously tiny compared to various other factors that cause short- and long-term fluctuations.
As I've already pointed out, and have pointed out many times before, one hostile estimate of the human cost from biofuel effects on food prices - by a right-wing think tank with an agenda of opposing biofuels and climate change action generally, promoted on WUWT and
explicitly shown to Tim at his request by Jack Hays - was in the order of ~200,000 deaths per year, smaller by a factor of one hundred than Tim's lies.
