To reword Upton Sinclair: It is difficult to get an anti-intellectual to understand something when their instant-gratification poor habits depend upon their not understanding its existential threats: pandemics, antibiotic resistances, and climate change. It's too easy to say "FU, gimme my supersized Big Mac and I don't care how it's made, Bill Nye." This is what a drug addict says out of willful ignorance while participating in long-term omnicide and ecocide because they're hooked and too weak to make the necessary changes themselves.
