The only time I would have a problem with vegetarians/vegans is if their choices affect my ability to make a choice. eg. I can no longer get beef because there’s now a vegan law that forbids it (type of thing).
Just out of curiosity, how would you feel about laws that make beef more expensive? (because of lower subsidies, stricter animal welfare regulations, or maybe higher taxes to cover climate impact)
It's almost like a zombie movie for them (startrek.website)
