If you've read much of my posting on firearms, you'll quickly realize that I disagree strongly with some of the points Sam Harris makes in the below-linked post. He also makes some I strongly agree with, he makes them well and I suspect those on the Left will be more likely to listen to those things from someone who shares their ideology than they would be if the same arguments came from me.
What I know for sure is that no matter which side of the debate you're on, this will probably make you think and it will probably upset you a bit. The former is excellent and the latter means he's been more reasonable than most of us on the issue.
