A nice, fun way to raise money for effective causes. Were all attendees vegan? Did you consider actively getting a few non vegans there?
I feel (but do not know) like attending warm, inviting dinner parties with great vegan food is probably an effective (though perhaps not very scalable) way to get people to go vegan.
“If I donate $10,000 to save two lives, I’m morally justified in taking one life because it’s convenient or enjoyable.”
I see your point here, but it would more accurate to say (in the vegan offsetting case)
“If I donate $20 to save hundreds of lives, I’m morally justified in taking a dozen lives because it’s convenient or enjoyable.”
Whilst the logic does change, the magnitude does, and I feel like that’s important here.
“Seeing someone willingly make personal sacrifices for the sake of morality encourages others to act ethically, too.”
This makes sense in theory, I am not sure it’s correct in the case of veganism. Do many vegans here actually experience this? I definitely don’t. I’m willing to bet most vegans experience orders of magnitude more stigma, defensiveness and abuse than moral admiration.
