"Bring back open prayers...loud and faithfully asking and thanking God for protection. Until then we may suffer more tragedies like this. When will accept the fact and adhere to it that we'll always need to say prayers openly amongst ourselves acknowledging God, our Father is the ONLY way to protect us."
That's not what your Christ said:
Matthew 6:6
But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
Why is it you people know nothing of this book you all hold in such high regard?
"During the era when we had open prayers in schools nothing like this every happened."
Correlation does not equal causation. I'm sure there were many things we had or did back then that we no longer have or do. That by itself isn't enough to connect them to current events.
"Kick God out and the devil will come in...sooner or later."
So, basically, evil will happen. Eventually. At some indeterminate time in the near or possibly far future. Sometime. Maybe. Unless we kiss your god's ass.
Very persuasive.
"We need God and his almighty powers; not hiding God and prayers in a closet or just to ourselves."
Oddly enough, your god incarnate said to do just that. Then again, when do you people actually even follow anything Jesus supposedly said.
Odd that none of it ever applies to you. It's just other people that need to follow his advice.
"Let the schools, jobs, etc. say it loud..Our Father which art in heaven, etc. before, during and after we enter our destinations. Try it and just watch our God's protection and grace over our schools, jobs, etc."
I strongly suspect you'd see no difference. Your experiment is flawed a number of ways anyway. First, you must show your god exists; second you have left yourself easy outs. If nothing bad happens then god is "protecting" you; if bad things happen then you didn't pray hard enough or the right way or long enough or some other bullshit.
Religion is good at setting itself up in no lose situations. That's how it's kept going for so long.
