Yes, there are some out there. From the Euston Manifesto spearheaded by Norm Geras:

We decline to make excuses for, to indulgently “understand”, reactionary regimes and movements for which democracy is a hated enemy — regimes that oppress their own peoples and movements that aspire to do so. We draw a firm line between ourselves and those left-liberal voices today quick to offer an apologetic explanation for such political forces.

On anti-Americanism:

We reject without qualification the anti-Americanism now infecting so much left-liberal (and some conservative) thinking. This is not a case of seeing the US as a model society. We are aware of its problems and failings. But these are shared in some degree with all of the developed world. The United States of America is a great country and nation. It is the home of a strong democracy with a noble tradition behind it and lasting constitutional and social achievements to its name. Its peoples have produced a vibrant culture that is the pleasure, the source-book and the envy of millions. That US foreign policy has often opposed progressive movements and governments and supported regressive and authoritarian ones does not justify generalized prejudice against either the country or its people.

Will any Democrat politicians in America sign on?
