People consider vegans on Lemmy as too preachy. Even in vegan communities here, mods have to remove soooo many inappropriate comments (I read a few of these and they keep getting removed for good reasons). Comments that suggest going vegan on posts about animal abuse are downvoted.
At the same time, whenever there is something about Windows or Chromium based browsers, people here are doing exactly the same. “Just use Linux/Firefox/whatever”.
I’m a bit fan of flexatarianism, aka half vegetarian. It’s a lot easier on my body (which can barely digest red meat) and the environment.
It just means you mostly eat plant based with the occasional meat. For me it’s mostly sausage or chicken when I do eat meat.
