I had an idea to start a wiki

the "BatShitCrazypedia"

works like this (I am serious)
list up all our major issues, legislation and crisis that need to be dealt with

then start listing up the absolutely craziest things you can think of that might be said to discredit or defeat reality and what needs to be done

then brainstorm and list up and start preparing in advance for strategies to fight the slurs, smears, and dis-information campaigns.

It would be fun.
It would pre-emptively make fun of them and take the wind out of their sails.
It would prepare us for any possible attack (though we may miss some as it is hard to channel too much nuttiness when you are a member of the reality based community)
