One thing I've learned in my years on this forum is that even 'skeptics' have some amazing abilities to ignore reality, particularily when it comes to subjects that are not about the supernatural or woo science.
I mean, I'm sure you and I would disagree quite a bit about gun laws, but even my revulsion for firearms (the very thought that people on the street as I go to work may be armed chills me) doesn't make me argue for nonsense. Lowpro's posts seem, as I said, more idealistic than realistic. If he were in that situation, and I hope he never is, I think he might not act the way he says one should.
Another thing I've learned on these forums is to avoid extremes. Especially in social issues, the people shouting "white" and the people shouting "black" are almost always both wrong. So I try to point out the wrong on both sides.
