I don't know but I suspect a lot of youtube footage that will fall right into the, "See! It's just a religion really!" camp and how will that be countered?

It will be countered with other youtube footage. It's a mish mosh out there, so saying less and congregating least is the worst idea. You can't counter cheap edits any better than you can counter flea books. Which is to say, don't stop countering. You can do a better job. They have nothing but propaganda, so counter it with reason and evidence. Don't let them control the conversation.

I'm not a gatherer, by nature. But in this case, I wish I could be there. In my bones, I feel like it's an important cultural/historical event that's calling us to take a stand. In 2012, it's more important than ever. Thousands and thousands gathering in Washington, D.C. to say, "We believe in reason."

It's a small thing but it's not a small thing. That's how politics and culture work.
