They call it the "National Day of Prayer" but don't allow members of the 4th largest church in the nation to participate. That's all there is to it. I think they should do away with the whole thing. Ever since a few years ago when the organization told members of the LDS church that they could not pray at the "National Day of Prayer," I see the entire thing as way too political.
Happy Belated National Day of "You Can't Pray With Us"
