Snyder also covers the following:
I covered this one in a previous article for Smirking Chimp, but it definitely merits repeating. A straw man is an inaccurate representation of an actual argument that, thanks to its new straw form, resembles but is much easier to destroy than the original. Thus, rebuttal requires only that the listener be ignorant of the genuine article and, among the Regressive Right, ignorance is like oxygen -- they desperately need it to survive.
So when über-regressive Svengali Karl Rove says liberals wanted to coddle terrorists post-9/11, he attacks a straw man since he knows no liberal ever said such a thing.
When regressives oppose evolution because 'humans didn't come from monkeys', they attack a straw man since no evolutionist has ever said such a ridiculous thing.
When they equivocate pro-choice with pro-abortion, they attack a straw man since pro-choicers are not for abortion, but support the right to choose whether or not to have an abortion.
When they say the progressive solution to gun violence is marching into your home and forcibly taking your weapons away, they attack a straw man, since no reasonable lefty advocates such a thing.
Sadly, the list could go on much, much longer.
