I can't see how the fact that with a few DIY skills it'd be easy enough to cobble up some kind of gun is not too relevant. The same applies to bombs, but that doesn’t imply they might as well be on sale at your local gun store or supermarket.

Actually it'd probably be easier to make a bomb that could kill a trainload of people than to put together the simplest kind of firearm. I doubt if the suicide bombers in London back in 2007 could have made anything in the firearms much more lethal than a peashooter.

Abortion is an issue that I don't think really fits in here, Bruce. You seem to imply an automatic alignment between those who tend to be hostile to guns and those who feel happy about abortion, and the reverse, and that's not a safe assumption. I imagine my views about abortion are not too unlike yours.
