Paul Krugman: They hate me! They really hate me!

Wow. Early in my tenure at the NYT, I was advised that it’s a bad idea to devote a column to attacking another columnist — not just at the Times, but anywhere. Why? Because it makes you look small — as if you have nothing better to do than snipe at other commentators, rather than trying to deal with real problems.

But I’ve obviously touched a nerve with my recent writing on Social Security. The Beltway crowd loves their Social Security crisis, and they won’t give it up without a fight.
