I read a couple articles on it when you first mentioned it. I see what you're saying, I just don't think it applies in this case. I think you're either trying to say that outrage over great evil is either always unwarranted, or that perceiving something as being a great evil is always wrong, or that the concerns about the treatment of animals in modern society doesn't count as a great evil. But I disagree with all of those things. There are some pretty significant differences between an outraged zealot and an outraged rights activist that come into play here.
> not really listening
I have listened for multiple decades. I listen to others talk about it at _great_ length. You can continue to simply believe that I am deaf to reason, or acting unreasonable in some way, but that's simply incorrect. You make it seem as if I am digging my heels in despite evidence that anything I say is wrong/unsound/false, but that's simply not the case.
