Different people react to different things. It takes many approaches to reach multiple types of humans.

I personally reacted after months of being shown hypocrisy, with the tipping point being when I said there’s no problem with eggs and dairy before I was shown what the egg and dairy industries do.

Part of that process was really realizing, not just knowing but consciously thinking about and considering the fact that humans are also meat. I am meat. The cats I loved were meat. My human family is meat. It’s not okay to eat them in a sandwich. Why is it okay to eat strangers in a sandwich?

No one approach will work on every human, and many people take a lot of different approaches over time to really understand.
