Atheism is unstoppable.

Not all are fading, though. Whilst traditional Christian churches have shown massive declines in the 20th century, Islam shows a lot of growth in the last 20 years, which is a cause for concern.

Why do you think that is? I feel that Islam is less flexible that Christianity, so is resistant to dilution and probably retains better. But is the growth due to immigration? I find it hard to believe it is actually drawing a significant number of people in from the outside.

It's because the developed "west", led by the US and the UK, have been fucking with the Middle East and other third world areas for decades, for their own gain, and to the general detriment of the ME and other less developed nations.  People eventually get tired of being pushed around and having their resources raped by foreign nations.  Social organization is essential for taking control of one's society, and religions provide one means -- and a very effective means -- for social organization.  

One of the big reasons the Soviet Union suppressed religion for so many years was NOT -- contrary to what some theists claim -- because they were zealots for atheism.  It was because they saw religion as a possible focal point for resistance to the political status quo.  And rightly so.

Religion is a social and political force; we need to understand that to deal with it effectively.
