I am defending the supposition because crazy people are crazy, regardless of whether they have guns or play violent video games or are into bondage porn. I don't think crazy people should have loaded AK47s in their house. But by the same token, I don't think people should be denied ownership of certain items just because loonies use them to kill people. I'm all for keeping weapons out of the hands of the insane, the foolish, and the dangerous, just as I am ok with cops arresting drunks, people blitzed out of their heads with drugs, or just plain sleepy people out for a drive in their car. That doesn't mean I support banning cars from the road wholesale. And you're right, I did use the wrong "do". Serves me right for sleeping in this morning instead of getting up an hour early, what with the time change and all. PS. This is getting into Soapbox territory so no more replies from me on this subject. (For the record, I don't usually wander into the Soapbox, so I guess that means I'm done.)
Imagine that you are hired to build a bridge over a river which gets slightly wider every day; sometimes it shrinks but nobody can predict when. Your client provides no concrete or steel, only timber and cut stone (but they won't tell you what kind). The coefficient of gravity changes randomly from hour to hour, as does the viscosity of air. Your only tools are a hacksaw, a chainsaw, a rubber mallet, and a length of rope. Welcome to my world. -Me explaining my job to an engineer
