Forty or so years of propaganda has been very effective at presenting some of the craziest crap as "common knowledge." Its power is that it's usually so twisted, it's damned near impossible to de-tangle and point out the various fallacies. As your example shows.
Damn. It just makes me furious that we expose one to have another take its place or that we go a few years without one only to have it rear its ugly head again and need to be addressed again. How many times to we have to kill these things before people quit taking the bait?
It's painful enough when we're debating "them;" but to have to keep debating "our own." *sigh*
