No, really, they are! Stop laughing! Why are you all giggle-snorting into your hands about this?
They really are! It's just that they have a very special definition of what violates the separation of church and state, that's all.
The National Day of Prayer doesn't violate the separation of church and state. Having "In God We Trust" as our national motto is totally cool. The Lord's Prayer is generic enough not to violate the separation of church and state, and declaring the Year of the Bible is in no way endorsing a particular religion.
The Environmental Protection Agency partnering with Universal Studios to promote the movie based on Dr. Seuss's classic story The Lorax ("I speak for the trees!"), on the other hand, is an impermissible use of government funds to "[promote] a clear ideology that has a particular religious flavor to it," in clear violation of the separation of church and state, and that is absolutely unacceptable!
The only conclusion that can reasonably be drawn from this - aside from "these people are fucking ridiculous", of course - is that they genuinely believe that they are entirely exempt from the concept of separation of church and state, but liberals aren't. (This is also supported by their collective panty-wad over Obama quoting the Bible to support his economic policies at the Annual Prayer Breakfast a couple weeks ago, which they called "over the line", lol.)
D'you think their copy of the Constitution reads "Congress shall make no law respecting an establishment of religion other than fundamentalist conservative Christianity"?
