Man, has no hope

Out running errands today. When an ordinary older Chevy pick up, slowly passes me in a two lane. Nothing special, just a 10-15 year old pickup. A back window sticker on the truck reads. “ My truck was built with wrenches. “ Is man kind, really this stupid ? Stupidity, that you feel a need to express to others ? Lord, save us all. How did mankind get this far ? Just one little example. It’s all over the place. Lol !
