So today I'm out in the field with other people who study environmental science (like, you know, people who should be at least a little objective about science in general) and one of my classmates starts speculating on why dogs can eat feces but humans don't. His first hypothesis was that humans are "brainwashed" but I pointed out that when we think something smells bad it protects us from eating poison or from eating spoiled food or anything toxic in general. Then I said, "also, dogs are carnivores so their stomach acids are more acidic..." Automatically, he cuts me off, and says "I'm not going to talk to you about this" and walks away. LOL WTF. I was actually in a pleasant mood and wasn't even trying to give a vegan lecture, I was just offering scientifically plausible answers to his question. He wouldn't even listen to a credible scientific explanation because I was offering it and he knows I'm a vegan. Well. Then I came here and looked around for a "gripe" thread and couldn't find one...so fellow forum members, please feel free to use this thread to post about similar gripes.
