Your reflexive anti-vegetarianism has led you to totally misread the point. He said "that much" animal product, so it's safe to infer that he would not have a problem eating a smaller amount of meat. He didn't say it was disgusting to eat meat, he said it would be disgusting to gorge yourself for days on meat to stretch out your stomach.

And I agree with him, animals are delicious but if I eat too much meat at once I feel greasy and disgusting for days.

We've also been murdering other people because of where they were born, babies that had birth defects and enslaving other humans for centuries - past practice from pre-industrialized society is hardly a compelling argument for continued abhorrent and selfish behavior. Rational argument apparently not your strong point.
