so just as a thought experiment, if you saw what was essentially a modern day holocaust, how would you go about convincing people that willfully(or through lack of knowledge) ignore it? Would you just say "oh I’d better not cause a scene, that would be really egotistical of me "? also cut change != cut off, there are vegan options for a huge range of palates, we are just so used to the current meat diet that anything else feels alien, despite other societies doing fine with these diets.
