Parents upset over no religious symbols policy. Why?

I read this more and more - parents are upset over some policy, this time federal, restricting religious symbols / words / books in schools.  But why?  I truly don't think we should be so upset over this.

The more it happens, the more I wonder if it isn't an abdication of responsibility.
Or maybe an argument of convenience.
Or maybe a total lack of understanding about Christianity.
Or maybe even a total lack of knowledge about the God of Abraham.
Dare I say - in some cases - that the parents just don't care?

The article that prompted this post is from WSB-TV in Atlanta.

Here's an excerpt from one of the parents -

Sims believes a teacher ought to be allowed to display a Bible verse. But in this case, the government calls the shots.

"I understand that's what they do. But I think this country needs God," Sims said.

OK - I agree - the country needs God.
However - is this the way to do it?

But, especially in this day and age, why would anyone think that - if the government was going to promote any religion or "god", it would be the God of Christianity that these parents are allegedly hoping for?  
I say allegedly, because I question whether they truly understand or care about the God they claim to believe in.
I ask why, because I don't understand why the government should be in the business of promoting any "god".  Look at the middle east - where the religion often promoted is Islam.  Look at areas in European countries and maybe coming soon to a neighborhood near you (even in the U. S.) where Sharia law is the one in practice.  Look at the image at the top.  Those are just some of the names of various "gods" that show up when doing a Google image search on the word "gods".  Jesus was first - likely because of my personalized view from Google.  For another person, or in another country, it's highly likely that something else would have been first.  In some countries, where they have agreements with Google, Cisco and others to prevent certain things from being found - it's likely that Jesus wouldn't show up anywhere on the list.

People have different views of "god".

People have conceptions of any "god".  Right or wrong, they think what they do, based on various factors in their lives.  It's always been that way - and government isn't about to change it.
Worse - when government does decide on an official religion with an official god - it does absolutely nothing for that god.  It's forced.   It's not that the people really change - they're just afraid and often go along with whatever they need to do to stay alive and safe.  
Any true worship of the God of Christianity goes underground.  Witness the early church from the Bible.  Witness Communist Europe before it collapsed.  Witness China today - where the official government "Christianity" isn't Christianity at all - but the true church in China operates underground in people's houses.

Problem #1 - God doesn't want to be one "god" of many

In case you've forgotten about this - here's a few reminders about how the God of the Bible feels about being one of many gods that people follow -

The Ten Commandments

Ex 20:1 And God spoke all these words:

Ex 20:2 “I am the LORD your God, who brought you out of Egypt, out of the land of slavery.
Ex 20:3 “You shall have no other gods before me.
Ex 20:4 “You shall not make for yourself an idol in the form of anything in heaven above or on the earth beneath or in the waters below. 5 You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the fathers to the third and fourth generation of those who hate me, 6 but showing love to a thousand generations of those who love me and keep my commandments.

Right at the top of the ten commandments - that a good sign that God considers this important.  And look at the difference in the way God looks at those who bow down or worship other gods.  Further, in this verse, it doesn't matter whether they worship God or the "other god" first.  God clearly wants to be first in our hearts and minds - and wants no other god / idol / entity to be worshiped by us.
