Muslim population creep or explosion
The issue in the USA is more about allegiance to the Constitution and form of government versus religious beliefs. Religions that attempt to pit loyalty to faith versus loyalty to government will meet resistance or create revolt.
What is the rate of non religious affiliation in the world?
“The demographics of atheism are difficult to quantify. Different people interpret "atheist" and related terms differently, and it can be hard to draw boundaries between atheism, non-religious beliefs, andnon-theistic religious and spiritual beliefs. Furthermore, atheists may not report themselves as such, to prevent suffering from social stigma, discrimination, and persecution in some countries,or, in cases where the situation is reversed, religious people may keep their beliefs secret in pro-atheist societies. Despite these problems, one study classified 2.5% of the world's population as atheists, and a separate 12.7% as non-religious.”
“A study has shown atheism in the west to be particularly prevalent among scientists, a tendency already quite marked at the beginning of the 20th century, developing into a dominant one during the course of the century. In 1914, James H. Leuba found that 58% of 1,000 randomly selected U.S. natural scientists expressed "disbelief or doubt in the existence of God" (defined as a personal God which interacts directly with human beings). The same study, repeated in 1996, gave a similar percentage of 60.7%. Expressions of positive disbelief rose from 52% to 72%.[1”
“Global Muslim population gains will outstrip non-Muslim growth over the next 20 years

The world's Muslim population will grow at double the rate of non-Muslims over the next 20 years, according to a broad new demographic analysis that is likely to spark controversy in Europe and the United States.
If current trends continue, the study found, the number of Muslims in the United States will more than double, from 2.6 million in 2010 to 6.2 million in 2030. The percentage of native-born Muslims in the U.S. is projected to rise from 35 percent today to 45 percent in 2030.
The Future of the Global Muslim Population may be the first to attempt to map the Muslim population of most of the world's countries. The analysis was conducted by two giant nonprofit groups interested in religion: the Pew Research Center and the John Templeton Foundation.
Among its other projections:
Muslim populations in some parts of Europe will reach the double digits, with France and Belgium at 10.3 percent by 2030.
Pakistan will overtake Indonesia as the world's most populous Muslim nation.
Muslim population growth and fertility rates will continue to decline.
The analysis could fuel critics of Islam in Europe and the United States, who argue that the religion is at odds with Western values and worry that the number of Muslim extremists is on the rise. Or it could calm those fears by providing evidence that Muslim populations in the West will remain relatively tiny.”
