“genocide as the mass slaughter of any life”
This is both not what genocide is and it also trivializes actual genocides. You’re right to call this view anthropocentric, but I’m not going to say that animal life is a 1:1 equivalency with human life. Industrial farming is fucked up I agree, and should be ended. I also agree that veganism is a good thing, better than eating meat. But overall it is not the same thing, not at all.
