They think they are saving the life of some poor innocent being. When they don'understand that vegan eating likely kills more animals in the process and is more harmful to the environment to produce. Monocropping that destroys soil. Chemicals herbicides and insecticides that do more harm.

Yes, these points should be emphasized when talking with vegans. Some vegans also think it is a healthier way to eat, so we should be versed on the falsehood of those claims, as well.

Vegan-oriented books and websites LIE to promote their religion, which is why most vegans are ignorant about the counter-points that we are discussing here.

If they became aware, some of them would drop the religion, while others will follow their cult off a cliff. So be it, just don't drag the rest of us, too!
