Two words Dave; Fundamental Christianity
As long as those bastards are allowed to base their hateful argument on several out-of-context references to "men lying with men" Amerikuns will think themselves justified in legitimizing organized condemnation.
Of all the "civilized" or "modern" nations on this globe we're the least tolerant.
Odd isn't it since we were settled (early-on) by those who'd suffered directly from the marginalization of intolerance.........
But you forget that those settlers were mostly the religious zealots who were being driven out for their own intolerance or their own strict interpretations. An excellent ongoing example, nearly unchanged in the 300+ years they've been in North America are the Amish. They even shun their own children if the children don't choose to obey the faith at the age of majority. While they are wonderful people, and very non-judgemental for such a strictly religious group, they ARE very strict in their belief. As were the pilgrims, and many other sects that came west in the 17th century.
Also, much of the world, including the U.S. is being manipulated by certain religious fundamentalists for reasons of power. The Xtian "right" in the U.S., the Imams and Mullahs of radical Islam in the Middle and Far East. In many Islamic countries, gay men are put to death. There are certainly some Xtian leaders here in the U.S. who would like to do that here as well, but there is still "some" semblance of the rule of law here, for now.
In contrast, most of Europe and Canada are less influenced by "the church", and fundamentalism in general.
I don't believe for one minute that all this growth in religiousity, and fundamentalism, is about a true belief in God. It is my belief that this is more about control, power, and fear. Religion has always historically been used to control the people, usually to the benefit of a select few. After all, one need only look to the Vatican to see the accumulation of wealth, in the form of art pieces and "artifacts", many made of gold and precious gems, to see that accumulating this wealth is at least as important as doing good works. And check out the mega-churches, with their multi-million dollar buildings, expensive vehicles for the pastors, elaborate multi-media systems in their chapels, and it becomes obvious that the emphasis is on accumulating wealth, not sharing it.
As ordinary individuals find survival getting harder, money tighter, stress levels higher, the become afraid for the future. Their fear makes them easy to manipulate. They are looking for someone to blame, and these "religious leaders" provide the simple, easy answers so many are seeking. The mullahs blame the West, Israel, and "the Jews" for all that is wrong in the Middle East. The bible thumpers blame abortion, divorce, the "faggots, lezzies and queers" for all that is wrong in the U.S. today. They each use words and images designed to elicit feelings of hate for their target groups. And it takes a strong, and independent, mind to resist such "programming". They never blame, or even acknowledge the growing disparity in wealth, both within their (or our) own countries, and between countries in the world. Nothing is ever done to address the increasing lack of power people have over their own lives, other than assign blame to that "other".
