I do agree that children should not be made to say it in school. That's just brain washing. I was saying the damn thing in kindergarten and didn't have the first clue what any of it meant.
Great idea, maybe new citizens can teach it to our children for whom many, their only aligners is to a new pair of Nike's or and Ipod. Ignorance breeds apathy. I see nothing objectionable in the pledge of allegiance, with the only possibilities of atheists not want to say "under God". For the rest is doesn't specify a Christian god, Hindu god, etc. If your god is your dog or global warming so be it. Very little is required from citizens in this country. It would be a damn shame if kids didn't know this phrase. Don't say "God" if it offends your sensibilities.
Brainwashing, what a joke that is. If you want to be technical that would cover everything except eating, sleeping, and taking a dump. Do you really believe saying something over and over makes you a true believer. Apparently you survived saying it in school as a kid.
Lets look at it line by line, because I believe some here might not know the words or what they imply:
I pledge allegiance to the flag, of the United States of America.
Pretty straight forward, it doesn't say don't change anything, or don't criticize the US. No single party or group has a monopoly on it, and that's is the way it should be. It says I am an American - if that offends anyone they really have no business here.
and to the Republic for which it stands.
Yes we are a Republic. I know some here voted for a Social Democracy and you may get your wish. Your little red book will contain the proper pledge when that occurs.
one nation,
Any disagreements yet? California believes in this concept... they want one nation to bailout their debt.
under God,
Athiests... leave this part out, just close your mouth for 2 seconds, it will pass quickly, the rest, this is what ever YOUR God is. I wish people were as offended here about cop killing, ho beating lyrics as they are these two words, might be some hope then.
indivisible,
This should only offend separatists, anarchists, and anyone else that would like to see the US broken up or dissolved. Here's a flash, most people don't, so don't go away mad, just go away.
with Liberty and Justice for all.
Anyone disagree with that? Maybe some think we are not at that point yet. For that group, is it wrong to set that as a goal and try to achieve it? Shouldn't we aspire to this? Without these ideals, minorities would be second class citizens or non-citizens now. Some will throw gay in here as an exception. Personally I don't, to me it's a life style and second they have the same rights as the majority does, they seek additional recognition IE special status.
I'll let the courts decide, since I don't have a horse in that race and even if I'm surrounded by gays, I won't be "brainwashed" into turning gay. Some of you that are easily "brainwashed" by repeation of things you hear every day might want to be careful. 
Happy Independance Day BTW. I suppose a few of you will be lighting up your US flags tonight.
