Then why do my responses keep getting deleted as below the civility threshold? 

Your 8-10% estimate  for a "natural" growth to reach 50% of the population is absolutely ludicrously high.

 With a 10% growth rate, and absolutely zero additional immigration,, the Muslim population in  63 years would go from approximately 1.2 million today, to 486 million. Again, are you sure you know how to compound numbers? 10% year over year growth, over 63 years translates to a multiplier of 405. Not percent. A multiple of 405. An 8% growth rate, over 63 years, equals a multiplier of 127 times. Clearly you do not understand compounded percentage growth.

You may not buy my numbers, but they absolutely stand up to scrutiny. Pick a percentage growth rate. Or a raw numerical growth rate. I say confidently that there will be at least 30 million Muslims in Canada by 2080. What will Canada's population be? 60 Million? 55 million? 100 million? 

Or, maybe a meteor will hit.
