If no seperation (sic) of church and state in the US:
- scientific literacy would would become a thing of the past
The Scientific Revolution was the direct result of Christian men (Copernicus, Newton, Kepler, Brahe, Descartes, Galileo, etc.) and the whole western world working from a Christian worldview.
- medical and scientific research would stagnate and regress. American medicine would become third rate. Diseases presently under control with immunizations would see exponential, society-threatening resurgences.
Are you assuming that Christian Science is the dominant religion of the United States? Edward Jenner--the man who scientifically described the first vaccination--attributed the vaccination to God with himself simply being the means.
- society would become increasingly dumbed down as critical thinking is forced out of education
OK, this one is a joke, right? Right? You don't seriously see "critical thinking" as a skill taught in the public school system, right? In the land of multiple choice standardized tests where regurgitation of information is the goal and thinking beyond the "comprehension" order is wholly unnecessary
- non-religious parents would be driven to home-school their children in order to keep them away from religious-centric indoctrination in public schools
This one I agree with wholeheartedly. And a lot of religious parents would do the same.
- there would be religious tests for public office and public and private employment and fierce inter-religious battles, some violent in the tradition of religions throughout the ages, for predominance
Not much of a change then, huh? We have two elected members of the Federal govermnet who openly admit to being Muslim. Just two. And I don't think I've ever seen a presidential candidate who didn't claim to be some kind of Christian. Shoot, Pete Stark of California is the only open atheist ever in Congress.
- laws would be enacted to fulfill religious agendas...same inter-religion battles as described above
We see this anyway. Don't think for a second that atheism isn't a religion.
- "free speech" would not extend to criticism of religions, religious practices, or the religious. Censorship would be rampant.
We call it "hate speech," and we're already being censored for it.
- non-religious people would be shunned, persecuted, and prosecuted
If they were to commit a crime, they may be prosecuted. But shunned? Seriously? You think you might not get to eat lunch at the cool kids' table?
- the internet, which has undoubtedly caused the rapid awakening and long-overdue expansion and visibility of the non-religious, would come under state control
Are you seriously that ill-informed? The internet is under state control. Has been since it was developed.
- the government would fund religions
Like Planned Parenthood?
- society would be irreparably fractured
We are *such* a united society as it is; any kind of disagreement would shatter our dreams of world peace
- the US would become more of the laughingstock and butt of jokes of the civilized world more than is now the case
Such a terrible thing. I do in fact spend all my time worrying what others think of me, especially those I've never met and never will.
- etc, etc...benefits to US society of having a theistic state: None whatever
