Eternity is more important than stupid rules. Why was it okay when I was in elementary school for my teachers to read the Bible every morning and say a short prayer? Look at schools now. Not much difference than juvenile detention centers. Coincidence? I obey God’s laws before man’s.
This is easy to say if the religion being promulgated in the school is yours. However, there is more than one religion willing to proselytize in the schools, and some go to lengths to do so without parental knowledge or approval.
How would you feel if a teacher were handing out Korans?
This being said, there are two sides to secularism. The good side is neutrality, where there is an agreement among the religious that children of one religion should not be taught religion by teachers of another religion, because they are a captive audience, by law, and subject to inappropriate influence.
The other side of secularism is the anti-religious side, that can be just as obnoxious in its proselytizing, attempting to sway children away from not just their religion, but to reject any religion. This is anything but neutral, but pretends to be.
In any event, for many years now, public schools have been forced into a state of neutrality. And still, where one particular religion dominates a school, there is almost a guarantee that students not of that religion will be in many ways leaned on by teachers and other students. And at the same time, there is always a continual pressure to be anti-religious as well.
So ignore neutrality at your own risk. As beneficial as the effect you are certain your faith would provide, there are other faiths just as determined to exploit an opening in schools as well.
