The person who calls himself "Use Your Brain" is obviously delusional in claiming that no Muslims ever leave Islam. I personally know a number of former Muslims who left Islam for different religions or for no religion, pumpkin...and that No True Scotsman nonsense just doesn't work.
The following link lists a number of former Muslims who have become Hindu...the larger article also has lists of former Muslims who have converted to other religions, too.
Use your brain - none of the former Muslims I know "sold" their faith for anything. All of them made the thoughtful decision to leave Islam, often against terrible family and social pressure. And not one of them would go back.
Your attempt to slime the character of people you've never met because they don't fit in with your narrow world view is despicable.
I know a huge number of "Christains who converted to Islam"?
will that source work for you?
I hope its useful....
The World Christian Database (WCD) and its predecessor the World Christian Encyclopedia contains large amounts of data on numbers and growths of religions. It is used as a source for many web and newspaper articles. The following is a tabulation of their results: (Note: The annual growth in the world population over the same period is 1.41%.)
Some sources mention estimates as high as 6-7 million.[48][49] (President Obama in a 2009 speech in Egypt, stated that there were nearly 7 million Muslims in the US.[50]) This would make Islam the second most popular religion in the US after Christianity.
