This is partially true. Let me correct that vegans faced serious health issue before the 50s when b12 source (bacteria) got discovered. They may have survived by eating dirty vegetable (without the washing, bacteria are still on the plant) but it’s very unlikely they got enough.

Veganism definition has nothing to do with industrial farming, however try ask vegans if they would have taken this way if industrial farming does not exist, you’ll make them think twice. In the circle I gather many says they would prefer eating flesh from an hunted wild animal than buying soap containing glycerin from pigs that never saw the sun.
