The whole thing is long but very good:
Risk, Prohibition, and Category 3: "In the case of Loughner, a tragedy welcomed ghoulishly by the left, leftists have even bigger ambitions in mind than they've ever admitted before.
Guns? That's nothing. Banning guns, or at least a lot of them, is a minor step on the way to a much bigger goal: What they're seeking to do in the current debate is prohibit any and all expressions of right-leaning political belief.
And it's an easy call for them, of course. Right-leaning political belief has zero legitimate value -- negative value, really! -- and the risks of such dangerous thought are frighteningly large!
Ban it. Ban the right. Ban them entirely. They contribute no positive value to society and in fact impose unbearably-high risks."
