I will dig into the meta a bit here, because both it, and one of your points is interesting.
When I read things like "animal agriculture being devastating for the world including the environment", it rings true, and makes me want to dig further, support this any way I can etc. The conflation with the (IMO hella sus) health arguments makes me question the judgment and intent of the writer, and second-guess my initial agreement.
I would find it easier to sympathize with the main purpose, if it was left to stand on its own. Trust is an important concept in human interactions.
*Reading further posts in this thread, I'm going to double down and add my own frustration: I really want to support this cause and perspective, but I hesitate because I consistently get signals that the people who promote it are arguing in bad faith.
Thanks for taking the time to respond. I'll consider your point. Although, just like a few other responses here it has the smell of a red herring to it, by shifting the focus from a inconvenient message to the form of that message.
