Same applies to the rest of the pledge. Keep them pledging their allegiance, adn they develop a REAL allegiance
I understand your point, and there may be people making the argument that we NEED the pledge to ENSURE the allegiance of our children.... but realistically, I don't see the recitation of the pledge producing any real results on the kids of the US.
I don't see it being pushed very hard either, really.
It's not being done right, but the principle of the thing is there.
The difference is that finding a religion satisfies a very common need that (some) humans have. It provides answers to questions that frighten people. OTOH, there's no scary unknown waiting for you if you don't find a country to wholeheartedly pledge your loyalty to before you die.
Even people that aren't bothered about death have questions that need answers.
Religion has historically answered questions centuries before science advanced far enough to begin offering hypotheses.
Example: Where did everything come from?
Religion: God made the stars, the Earth, the plants, the animals, and the people.
Science: Well, there was the big bang, and that created the universe. We don't know what started the big bang, and under current laws of physics, never CAN know.
Of course, the big bang just blew out a lot fo subatomic particles. Eventually, those formed atoms. From there, things started sticking together because of gravity. Again, we don't know why everything wasn't evenly distributed, which would have prevented anything from pulling together.
And then it clumped together and made stars and planets.
And then something happened, probably involving lightning. Some molecules began copying themselves.
And got more and more complex over many eons, until we got where we are today.
Of course, once science advances to the point where it can offer a more accurate picture than "God did it" religion starts fighting it, because it runs counter to indoctrination.
Sometimes religion fights dirty too. Forces people to publically recant their opposing viewpoint then locks them up for life and such.
And some people just don't like the scientific answer because it's complex, incomplete, and not very accessable.
