Every argument against veganism seems to rely on being a moron.

I'm not a vegan, I raise cattle.

But I can understand what veganism is and understand there is no good argument against it.

Simple

Actually the only "anti vegan" argument that isn't just pure retardation is that wool and leather are more environmentally friendly than synthetic oil based clothing.

And plastic pollution hurts animals.

Every other anti vegan argument is just retardation based on a misunderstanding of what vegan means
