It's a sad day when the following list from Air America makes perfect sense to consider when dealing with your ideologically twisted relatives. Any time a party advocates even more of their failed policy while still digging their way out of the last hole they dug, you know there's very little that can be done.
Here are a few of my favorite survival tips.
2) Avoid facts, as they will play absolutely no role in the discussion and may cause your interlocutor to charge, gore (physically), etc. Examples: The mortgage meltdown is Jimmy Carter's fault. 9-11 was a Bill Clinton special. Do not engage.
3) Do not, under any circumstances attempt humor! This also applies to snark and sarcasm,
4) Do not get rattled when your opponents declare their adoration for Glenn Beck, Sarah Palin, or Rush Limbaugh. They have been trained to do this. Do not fall for it.
5) Try your best to speak in platitudes, using words like "freedom," and "constitution." This should put you on the same wavelength as the person you're debating, confusing them, and draining their ammunition. Remember your civics class!
Basically, it's time Democrats end the argument by admitting that all those who believed in the Republican free market model, including cool-aide drinking Democrats, were proven wrong. Alan Greenspan admitted it, Timothy Geithner and Larry Sommers admitted it and anyone who can learn from history is admitting it.
