I see that you are really desiring a reply on this part so here goes. Most people I know realize that kids are allowed to pray silently. I am sure that there are several folks on here who remember times when a prayer was said before sporting events and such. Now, unless a school openly defies govt. (and I know some who still do) they cannot. I am sure that there are even some who can remember when a school day was started with the pledge of allegiance and perhaps a word of prayer. Not anymore. I think that is they type of prayer that most people will complain about that has been taken from the public school.
As to Christmas....no more class Christmas parties (for some) which was a big deal for the kids not so many years ago. Also, no Christmas plays that focus on the birth of Christ.
You know, as a very fundamental Christian, I am not at all upset that these things are "taken out" of school. I would rather, and do teach my kids about this stuff at home. But I can certainly understand where these peope are coming from who complain that this stuff is gone. It's easy for me as I am around these folks every day.
