We have to be everything when it should be obvious.
We have to be moral philosophers.
We have to be nutrition scientists.
We have to be good communicators.
We have to be good at arguing while also maintaining some level of respect.
We have to be climate scientists.
We have to be experts on how animal agriculture works.
We have to be biologists.
We have to be absolutely perfect people in every other aspect of our lives.
And more.
Just to convince other people that it's wrong to abuse, torture, rape, and murder other innocent sentient and conscious beings for momentary taste pleasure.
It's ridiculous and pathetic that we even need to dedicate as much time as many of us do to convincing people of something that really should be totally obvious. And even more ridiculously, people give us insane pushback and resistance despite already having to become well-versed in all these subjects to respond to their asinine rebuttals.
