You can be the change you want to see. If you find a community that is close to what you want, you can actively participate and offer suggestions to help “onboarding” of new vegans. I try to do the same with Marxism, even making an intro reading list that I frequently share (and keep linked on my profile), because I know other comrades are more tired and hostile as a consequence. I refuse to blame hostile reaction when existence itself is under siege regularly, be it veganism or Marxism, and would rather take on the proactive mantle myself.
