I think I started to do something like this before, but got side-tracked. Dunno. But wouldn't it be helpful to have a list of timely fallacies--either newly minted ones or classics that are particularly popular these days?
Re: newly minted ones, I was thinking of e.g:
The Support Our Troops Fallacy
(If you oppose the war you oppose the troops)
The Chickenhawk Fallacy
(You can't suport a war unless you've been in one yourself)
The I-Think-The-American-People-Realize Fallacy
(When you want to convince the people of something you tell them that they already believe it)
The Our Enemies are Worse Fallacy
(You try to justify a policy by pointing out how much worse our enemies are)
There's lots more of these I'm sure. Some of these actually turn out to be a little complicated.
