Not sure if such topic has been made already, ...probably not. Every day I hear meat-eaters say stuff that they have no idea how incorrect it is and I'm honestly sick of it. So here it goes:
"Humans are born to eat everything. They are designed to eat meat." - Mother. Actually, all humans are born vegan. Cavemen have learnt that animal meat can be consumed and used for food, and ever since then, meat-eaters count animal meat as food. But just because something can be eaten, doesn't mean it should.
"If you don't eat meat or drink milk, your bones will start to break." - Grandmother. I would like to see some evidence that dairy milk is good for the bones. As a matter of fact, many studies have shown that animal protein can cause bone loss in humans.
"Look at your nails, they're purple! You know why that is? Because you don't take iron. And meat is the only way for you to get iron." - Grandmother. Well, it's true that my nails are purple because of the lack of iron, but it's wrong to say that only meat contains iron. Beans, lentils, peas and soybeans are also foods that are rich in iron.
