No one was called an "idiot". Bob just pointed out that you clearly lack an understanding of what is defiend as "protein" in the pet food industry.
Your fingernails are protein, but they aren't digestible. I could make you a mix of corn starch and fingernail clippings that would meet the pet food industry standard!
