I've told them, "Think of all the lives you'd save with all cars being limited to 20 mph. After all, you (the person I'm talking to) set the standard at IF WE COULD JUST SAVE ONE LIFE"
(not using caps to yell. Because it was a quote in a quote, didn't know what to do)
And when they tell me their car doesn't kill people....
Really.. neither do my guns.
When they say cars kill on "accident", I say, "WOW, I'm sure that makes a big difference when you are DEAD. I'm sure God/god/mother nature/random chance will send you right back if it's just an accident."
The reply to this is "Yeah, well, the deer don't normally carry a gun or fight back."
