Point for Point, or I Have Marshall McLuhan Right Here.

Linked via Driftglass:  American Dad at TPM brings what even Drifty calls a BFG to the fight with conservative attack weasels.

I'm only going to quote the section on history.  He's pretty thorough:

History

If you're going to use words like socialism, communism and fascism, you must have at least a basic understanding of what those words mean (hint: they're NOT synonymous!)

You can't cut a leading Founding Father out the history books because you've decided you don't like his ideas.

You cant repeatedly assert that the president refuses to say the word "terrorism" or say we're at war with terror when we have an awful lot of videotape showing him repeatedly assailing terrorism and using those exact words.

If you're going to invoke the names of historical figures, it does not serve you well to whitewash them. Especially this one.

You can't just pretend historical events didn't happen in an effort to make a political opponent look dishonest or to make your side look better. Especially these events. (And, no, repeating it doesn't make it better.)

You can't say things that are simply and demonstrably false: health care reform will not push people out of their private insurance and into a government-run program ; health care reform (which contains a good many of your ideas and very few from the Left) is a long way from "socialist utopia"; health care reform is not "reparations"; nor does health care reform create "death panels".

There are loads of links at the original if you need specifics and citations.
