I was under the impression that it was about the demographics that are unresponsive to efforts to reduce meat consumption, but I suppose I could be mistaken.

I consider the Boterman paper and other similar works (https://journals.sagepub.com/doi/abs/10.1177/136843021882440..., https://www.sciencedirect.com/science/article/pii/S019566632..., etc) to be sufficient basis. One does not need to eliminate meat entirely to significantly reduce it. Also, I consider right-wingers to be more reactionary than conservative.

I think I'm ethically justified in bigoted towards people that want me to die, but whatever,
