It’s very hard to get b vitamins withou animal products. Your body, especially your brain, needs them. IMO, vegetarians are irrational and unreasonable due to a deficiency of b vitamins.
I knew a vegetarian who would order pepperoni pizzas and throw the pepperonis in the garbage. Sure, pig, thanks for dying so she could throw you away. She also ate pork and beans and was clueless about the little white cubes. Idiot.
