Lawn mowers are old news, like toasters, curling irons, microwaves, and scissors. Besides, it's no fun to pick on common things in such widespread use. If we did that, sooner or later we'd have to admit that all the controls and regulations in the world can't protect us from our own stupidity.
Motorcycles, skateboards, pit bulls, and electronic cigs are a totally different game. Their users can be group-classified as reckless, risk-taking, eccentric outcast cultists who intend to wreak havoc and destruction upon innocent children. I think it's less about regulating the devices, and more about watchdogging the groups using them.
I didn't really want to end up in this can of worms, but cmon man, really? Would you be willing to frame that differently? Perhaps without all the tugging of heartstrings and introduce something empirical here.
What needs to be realized is that there are idiots everywhere. Including operating the keys on this laptop. We're all stupid in one way or another. We're all incredibly smart in one way or another/others. The sooner you learn to embrace that fact and use that knowledge to further your enjoyment in life, the sooner that life gets a lot easier for you.
Stop it with the "but the chilren" crap. We deride that all the time as a weaksauce argument coming from thinktanks, poorly extecuted/interpreted studies and legislators. If it can't fly for them, it doesn't fly
from us either. I can do my level best to encourage safe vaping to all the people I run into that it applies to, but at the end of the day, I can't actually
make them change their ways. I did my part. Just like I can't make your Uncle Bill lock up his firearms, I can't make your wife's cousin not drink and drive and I can't stop the creepy dude at the convenience store from ogling females and just being, well, creepy.
And, I have a pit bull type dog. (He's a Staffordshire Bull Terrier. Ask a brit...) It's not that I"m offended by your assertion that I'm reckless for having him, I'm offended by the total lack of fact or logic in your post. And, it's not just you. I know I'm on a bit of a soapbox right now, but some of y'alls horses are so flippin' tall right now...
Carry on.
