This is exactly what people love using this argument for… It’s a toxic concept that if we can’t make a big enough impact, we shouldn’t even try.
I think one could correctly argue that this is one of the major things wrong with the world today. If we aren’t willing to fight injustice, how can we expect anything less from the world around us going forward?
In this case “fighting injustice” just means buying greasy chicken from the place next door. It’s such a pathetically easy thing to do. Better yet, go buy some discount raw chicken and make something cheaper, healthier, and better tasting at home.
