"What's so hard to understand?"
Isn't that the same Amendment which includes the "separation of church and state"? Go ahead and read the whole amendment - - you'll see it in there somewhere. Or maybe not. In which case that would certainly show you what the scumbag politicians think about the Constitution of the United States, wouldn't it?
Actually the phrase 'seperation of church and state' doesn't appear in the 1st Amendment nor anywhere else in the Constitution.
