I don't have much to say about the recent Arizona shootings by madman Jared Loughner, except this:
Many commentators almost as mad as Loughner have attempted to connect this lunatic's actions to "inflammatory right-wing rhetoric." I won't go into here the long list of inflammatory left-wing rhetoric (and actions) that spill over into open violence. (Michelle Malkin has a good summary — with detailed proof — if you're interested.)
Instead, I'll make a suggestion.
If the Left wants to eliminate at a stroke the vast majority of heated, hated right-wing rhetoric there's a very simple way to do that: give up.
Get out of the way. Stop advocating the violation of individual rights every day in every way. Stop trying to get legislation passed that steals private property for the purpose of funding your favorite social engineering goals. Stop extolling the alleged virtue of interpreting the U.S. Constitution in ways that further Progressive goals. End your advocacy of coercion through government.
Your cause is not noble, your methods are not virtuous, your philosophy is not just. Your ideas are more than mistaken; they're immoral, impractical, and unconstitutional. Change your philosophy and change your behavior and 'the Right' will have no longer have an incentive to fight back against your support for squishy tyranny.
Until then, you can expect the rhetoric to continue. A vocal segment of the American people will simply no longer sit back passively and watch their freedom get corroded away, one bad edict at a time.
Until then, the intellectual revolution to restore it will continue undiminished.
