with the risk of feeding the troll, maybe this will sway some fence sitters from adopting this argument
because we allow people to shave (some even do it with straight razors, too - dangerous shite) themselves and others with little to no oversight but we don't let them perform surgery without proper training that takes a decade or so to master. should that make surgery illegal?
also, if you want to talk safety for home implements just look at the number of people that die due to carbon monoxide poisoning (or sometimes explosions) because of improperly set up heating at home. did you know it's illegal to operate on your own gas pipes without proper permits? yup, you need to be qualified for that so you don't rig your house into an IED
or if you want to have some fun, play around with some improperly discharged fridge capacitors, and see what that gets you. yet, you still have a fridge, I'd wager. by your logic, if it's allowed in a home, it's safe, right?
