I may not be exactly verbatim, but I seem to remember "congress shall make no law abridging the freedom of speech." I am pretty sure that this means that the ACLU/AU can go stick their "humanistic" principles up the ungodly...well, you get the idea.
I'm sorry, but I just don't get these ACLU types. How in the heck am I "establishing" a religion if I am a teacher, an administrator or even a student and sayiing "God bless America"? I thought the establishment of a religion is a heck of a lot harder than that.
