@terry0,
Ah-hahahahahahahahahahaha , , ,
Agriculture is at least 10,000 years old, more than enough time for humans to have evolved to eat grains. Humans ate grains well before they began to practice agriculture. Feedlot animals are doped up with antibiotics because they are packed together in feedlots, which is unnatural, so diseases can spread like wildfire--it has nothing to do with eating grain. What the hell do you think those animals eat in their natural state?
Come on, 'fess up--you just make your **** up as you go along, right?
