“Cars should have more seatbelts!” “Yet you buy from brand X who refuses to provide belts and lobbies against belts, you could buy Y instead!”

“We should improve our society. (Said by a rich provileged person)” “Yet you don’t push back against horrible practices, just talk a bit and otherwise enjoy your privilege.”
