AFAIK, there is only one major cultural group with a history somewhat compatible with veganism (Jainism (?)) and almost every other culture has a carnist dominance. Sure, people in earlier periods ate less meat and did not have the nutritional abundance of today to sustain philosophies like veganism, but a lack of food culture is still somewhat a shortcoming.
I’ve been vegan for 8-9 years now and I’m now more aware that veganism as a philosophy sprung out of industrial society: On the one hand as moral reaction to agricultural industrialisation, but also building on top of the agricultural surplus and relative stability of logistics networks. There is also the increase in levels of education since the industrial revolution to consider.
Anyways, given the cultural recency and tendency of cultural nihilism of industrial society, I doubt that many longstanding food culture traditions can or will be convertable in the long run. This on its own isn’t good or bad, but we’re living in an odd era when it comes to veganism: Veganism is relevant enough to be viable without too much practical hassle, but it is still very far from socially normalised in most societal groups aside from certain leftist groups. It is still a conscious and conscientious and perseverant decision to be vegan. Everyone probably experienced a carnist cultural event where they had to explain how or if they specifically will participate - I see this as the indicator that veganism in its respective cultures is not normalised yet.
FOR BAD FAITH ACTORS ONLY
No, this not an argument against veganism (it is a vegan-centric to-do list), because it doesn’t negate the arguments for veganism.
For a bit of perspective: I was brought up vegetarian and was surrounded by other vegetarians as a child. My parents were vegetarian and I’m bringing up my children vegetarian (more vegan actually).
Eating meat has essentially become unthinkable in the micro-culture and tradition of my family, and I expect this to continue. There is no ‘perseverence’ in it - it’s simply a fact about what we consider to be food.
I expect there to be non-meat options and don’t feel socially excluded because my diet is non-typical, because this is how I was brought up and how my values were shaped as a child. It was more controversial in my parents day, but I’m grateful that they made the decision and that mainstream culture has become mostly accepting of it now.
I guess what I want to say is a) you exert an influence on culture, even if it takes time, generations even, and b) you can afford to not be overly sensitive to social judgement.
