The Biblical Rock Ban

Alright, you big dummy, you see that pile of rocks? The meme is pointing out a hypothetical, saying, "What if God had banned rocks because Cain used one to kill Abel?" You know, like how some folks wanna ban stuff after one bad incident. But then, if rocks were banned, David, that little guy, wouldn't have had a rock to smack Goliath with! See? It's a clever way to poke fun at overreacting, using old Bible stories. You're welcome, smarty pants.
