No cotton picken way!
America is not now nor has it ever been secular. Our forefathers came to this country to escape religious persecution and that has not changed all that much in modern times. I will grant you that the majority of the people coming to the United States are now coming for economic reasons, but a large portion of the arrivals ARE running from the religious fanatics in their own homelands.
What has changed is the fact that a significant block of committed individuals has decided to attack anything that smacks of a government supported or state sanctioned religion. That doesn't mean that the majority of the American people are in any way secular. As a matter of fact, there has been a resurgence of religious fervor over the last 10 years or so. If you follow news events rather closely, you will quickly realise that the number of people who are actively involved in these attacks on our religious freedoms are a very very small minority. Where their power comes in is the fact that their attacks are funded, organized and run with a military precision that has to be seen to be believed. This gives the illusion that America has become secular and nothing is further from the truth.
Within my own hometown, there are so many churches, synogogues, etc. that it is referred to as the town of churches. We even have one round church where they say the devil can not corner you no matter how hard he tries.
Within the last three years, eight new houses of worship have been built and not one single church has closed it's doors.
