I say I don't approve of illegal immigration.
Dude says I hate Mexicans (and therefore am a racist).
This is the part where I'm supposed to gasp and meekly suggest that I'm not a racist.
Then he suggests that I prove it.
Then I'm supposed to issue a statement that not only am I not a racist, but that I will be contributing money to La Raza to prove it.
At this point, he points at me and exclaims that I'm a racist and gave money to La Raza, which is clearly proof of pandering.
etc.
etc.
etc.
The way to avoid that trap is to break the chain by refusing to abide the initial assertion (thesis) that I am a racist.
All that said, This is a message board, not a real high-stakes political arena. Do I think Palmer wants me to contribute to La Raza? No. Was I extrapolating a bit on his behalf? Yeah. Do I really think he was consciously employing any "tactic"? Nah. Was he being disingenuous? No. I think he actually believes that stuff and has been trained (I would guess by modern academia) to respond to stimuli in certain ways, which come across to me in this case as the Hagelian Dialectic.
I call it a "liberal tactic" because those are the people I catch using it most often. Well, that and the fact that it's been used by Marxists and Communists for generations now. Some right-wing authors/bloggers/pundits (Moonbattery.com is a prime example) try it as well, but don't have nearly the success. The prevailing political (political correctness) climate favors those on the left.
