Why do so many people have a problem with God in our country?

i dont understand...i mean our country was founded by Christians escaping religious persecution...our founding fathers were Christians and when they wrote our constitution and declaration of independence, they did it with religious beliefs.. its ok if you dont believe in God but you dont have to make such a big deal and hate the USA for it ya know..just ignore it and live the life you want and dont let it get to you, b/c if you like it or not...it will still be there
