As it stands, mandatory recitation of the Pledge of Allegiance in public schools is completely unconstitutional. It is religion forced on a nation that is supposed to separate church and state.
The new argument I heard on my favorite talk radio show today is something like this:
The majority wants "under God" in the Pledge of Allegiance. This is a Democracy, and the majority rules. Therefore, the phrase stays.
Democracy is an important system of government; not only to the majority, but to protect the minority as well. Recall folks, several hundred years ago, the majority of human beings in the USA thought it was ok to enslave other human beings.
Keep that in mind next time - Democracy means you can have all the silly ideas you want. But when your rights (even the majority's) infringe upon the rights of others, it is inherently wrong.
Now, if you still believe "The majority wants "under God" in the Pledge of Allegiance. This is a Democracy, and the majority rules. Therefore, the phrase stays", I politely ask you to suck on my athiest nuts.
