Butterflies and Wheels
There are two things on B&W that I strongly recommend to anyone reading this. The first is The Fashionable Dictionary, which defines terms as used by people with a tendency towards "woolly thinking," like alties. Example:
Something to be examined when it is our opponent's and taken for granted when it is our own.
As you will see, these definitions can be very helpful in countering the "arguments" of pseudoscientists and alties. They are also helpful for those of us of a skeptical bent, to try to keep us "honest" by pointing out ways we can go astray in our arguments without necessarily realizing it. The other section is The Woolly-Thinker's Guide to Rhetoric. After reading these techniques, you too can argue like a pseudoscientist, pseudohistorian, or altie! Or, if you're like me, recognizing these techniques can allow you to point them out and thus counter them.
In addition, B&W links to all sorts of interesting articles countering or demonstrating politically motivated pseudoscience or ideology trumping evidence.
