Having said that, the US has lost a lot of its credibility in the international arena with the antics of the "Crime Family Bush" and the politicisation of religion.
The US religious landscape is totally different from that in Australia. At least here we have a lot more tolerance.
I prefer the European Convention on Human Rights stance:
Article 9 – Freedom of thought, conscience and religion1
1. Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion
or belief and freedom, either alone or in community with others and in public or private, to manifest his religion or belief, in worship, teaching, practice and observance.
2. Freedom to manifest one's religion or beliefs shall be subject only to such limitations as are prescribed by law and are necessary in a democratic society in the interests of public safety, for the protection of public order, health or morals, or for the protection of the rights and freedoms of others.
This is actually a serious issue for certain religious sects, including Muslims and extreme Christian sects like the Brethren. Apostates face persecution, which may include total withdrawal of contact from their families, abuse, or even death threats.
Ray -
The passive atheist (who cares not whether there's a god, nor for religion) is different to the active atheist, who does care, and who pro-actively proselytes against religion or belief in God. They want their beliefs transcendent, because in our speck in the Milky Way Galaxy, they have a corner on "truth".
That about sums it up. I can't see how passive atheism could qualify as a religion. An active atheist as you describe could possibly qualify as being 'religious', but that's just a small sub-set of the total belief system. Most atheists and agnostics couldn't care less about trying to convert people. In my experience, the most fervent 'froth at the mouth' atheists are ex Baptists
As an illustration, I bought my wife (who is Roman Catholic) some rosary beads when we visited the Vatican city. I don't think an active atheist would do that?
