Calling them "wuzzles" will not help, either.
Of all people, you must know what it is like to be wrong, because you admit it.
You say there was once a time when you were a pro-war neocon, but "now, you've seen the light." I am sure you experienced people telling you, back then, how wrong you were. When they said you were "beneath contempt, intellectually and morally," did it make you want to go join them? Or did it make you want to dig in and be hard-headed in defending your erroneous position?
People who polarize make the news and tend to attract followers. For that reason, your approach may be just right for you from a marketing perspective. I have to admit, you have an uncanny sense of humor when it comes to being a critic and stereotyping. That's a part of the comedy. It is entertaining. It lacks PURE intellectual honesty, but if it didn't, it would be dry. So, you're in a dilemma between pure intellectual honesty vs. entertainment and popularity. It's the same dilemma that faces MSNBC and Fox News.
There's no easy answer. I think your work, and your approach, are very valuable. To maintain the entertainment and humor, maybe you can count these lefties as among potential friends to your cause and leave the bashing and biting humor to those in control over America who deserve it. Part of a good war strategy is to define the enemy correctly.
After all, look at all those things lefties have done to promote nullification - as in pot, gay marriage, abortion, civil rights, and such. These people can't be THAT stupid. It's just a matter of re-orienting them to a common cause. Easier said than done, I know.
Anyway, I really do admire your speaking abilities. You have a gift.
Keep up the good work, Tom.
