Ultimately, people don't like what is different, especially if it's proselyte. It creates a "us vs them" situation, the same type that creates xenophobia and racism. I don't think that it is something that can be overcome without it coming from a central authority (religious or political). Something would have to be done on the same level as demonizing cigarettes to make people reduce / stop their meat consumption. (Lot's of advertisement explaining the moral issue, possible taxation on meat based on origin etc.). On top of that, traditional cuisine is one of the most fundamental identity concepts. Asking people to stop eating like their ancestors is a hard thing to do, without the value of it being better tasting. Overall, in a country that would have the political will to do so, the following solutions might work: - Heavy advertisement, like the one against cigarette - Taxes on meat, based on origin - Don't try to force people to eat healthily at the same time. While a ceasar salad without real chicken should exist, so should fat hamburgers and pizzas. - Invest on meat / cheese alternatives so that they become cheaper. Invest on marketing for kids as well for those. - Don't try to go all in at once. If all of the population reduce their meat based product consumption by 40%, it is a way bigger success than the current vegan movement. But without doing that, and just by having vegan as a proselyte community, you force people to choose a camp, either vegan or not. They'll chose that based on their relationship with the overall community and own internal moral compass, which is not very efficient and creates a lot of conflict.
