Outside of specific, documented medical need, I’ve found first hand that most vegans are mentally ill extremists.
I qualify specific medical need. We aren’t all the same, and some people are subject to unfortunate circumstance. Otoh, most people I know who went vegan are pansy @ss leftists with no real justification outside of leftist peer pressure over perceived cruelties with the food chain.
How many vegans do you know, and what are your qualifications to diagnose them as mentally ill ?
