Yeah, that's an oldie: So, people should be allowed to have guns. As many as they want. Where they want them, e.g. on airplanes, in schools and on the job.
There's a logical flaw in that:
Bombs don't kill people, people kill people. Ergo, people should be allowed to have bombs. As many as they want. Where they want them, e.g. on airplanes, in schools and on the job.
Chemical spills don't kill people, people kill people. Ergo, people should be allowed to have lots of chemicals in their back yard. As many as they want. Where they want them, e.g. on airplanes, in schools and on the job.
Nuclear disasters don't kill people, people kill people. Ergo, people should be allowed to have nuclear plants in their back yard. As many as they want. Where they want them, e.g. on airplanes, in schools and on the job.
I'm curious: Those, who advocate that "guns don't kill people, people kill people, so people should be allowed to have guns", do they similarly advocate that people should have bombs, chemicals, and nuclear plants?
If not, why only guns? Don't come up with this Amendment crap, because the Amendment has nothing to do with what guns and people do - it is only a political decision.
