I asked Grok for a list of top well-known vegetarians throughout history. There are a LOT of important white Europeans on this list, many from the cradle of western civilization.
You wouldn't shut out based right wing vegetarians from your political movement(s), would you? Whether yes or no, what's your rationale?
BTW, this is not an idle question. I'm doing some research for a personal project.
