I'm another paleo dieter. It seems like that diet is overrepresented among rationalists and individualists from my experience, but that is just personal empiricism.

I take a positive view towards the morality of meat consumption. We are doing it because it is practical and delicious - we simply have a weaker preference for not doing unnecessary harm to animals. Once vat-grown meat becomes widely available, I predict that our cultural sentiments surrounding meat consumption will rapidly change such that only vat-grown meat will be acceptable to eat.
