Hammers are very dangerous. Tens of thousands of hammer accidents happen a year in the US. Hammers can be used to dismantle and destroy things. They’ve even been used in the perpetration of crimes and murders. I could not on good conscience date someone who uses a hammer.
I knew a hammerhead shark once, it was actually very kind and considerate, even when hammering. I think humans will probably evolve into responsible hammer users in a few thousand generations or so. It’s just a matter of practice.
Hammerhead sharks are unironically one of the coolest animals in existence
