The top reply is addressing whether HFCS is more dangerous than other sweeteners rather than the claims Lustig makes. Lustig agrees that it's not more dangerous than something like table sugar. What he is saying is that fructose (whether from HFCS, sucrose, agave nectar, etc.) is toxic in sufficient quantities. So this isn't really debunking anything and it's actually in line with what Lustig says.
