I’m not even going to argue science with you at this point because you are so far off of what even nonvegans who care about the environment usually agree on and you clearly have an issue believing or understanding research.
Your trolly problem point is a nothing sandwich. Vegans get a win win in that refusal to eat animal products results in overall harm reduction in our real world. So it doesn’t matter whether or not they are rights-based or utilitarian vegans.
You can deny evidence and think what you want but now you are really just arguing for your sake instead of being honest with yourself.
If you are so into philosophy you would probably know your anecdote about your wife means nothing to me.
Also YOU see preachy vegans, stop assuming what others see. I’ve seen more people go vegan and its better evidence for this than your wife anecdote.
Again, JWs preach something no one sees. Animal agriculture is a real thing and its a false equivalence, Mr. Philosophy
