I probably should be vegan because I am lucky enough to have the economic privilege to support that kind of lifestyle.
But, as with many other communities centered around lifestyle topics, I would never want to participate in a vegan community. Lifestyle communities always become insular and echo-chambery, so you become a pariah if you don’t properly adhere to 100% of the community consensus behaviors.
Not just vegans, but you see it happen with fitness communities, diy/home decor, a lot of hobbies, etc.
