I'm eager to acknowledge the systemic challenges of being veg_n since those were barriers for me in the past myself. I'm privileged to not have those issues anymore, but I still recognize the premium that I pay to be veg_n (my partner and I refer to it as "the vegetarian tax").
I harbor no animosity towards people who can acknowledge the sustainability crisis of the meat industry but aren't in a position to personally separate from it. The expectation that I have for decent and informed people, in order from the bare minimum to the absolute most is:
Don't pointlessly disparage veg_ns or spread misinformed agrobusiness propaganda. This in fact takes negative effort.
Occasionally examine whether you have any opportunities to reduce your meat consumption.
Talk to people you personally know about the sustainability crisis and see if you can find others in your circle who are interested in reducing their meat consumption. Work together to figure out effective strategies for doing so in your situation.
