Older video explaining why Islam is growing so fast:
The reason Islam is growing so fast is not due to conversion, it is due to breeding. Muslims have far more children than any other group on earth. Their religion grows simply due to them replicating like rabbits.
Intelligent people tend to have less children. Atheists tend to be some of the most educated people on earth and as we know, they have some of the lowest birth rates.
This is what is wrong with the world, we have the least educated and intelligent population, (Muslims), having the most children. Their children grow up under their laws and beliefs to become future Muslim breeders.
What does this mean? I guess it means the intelligent people must begin having more children or will simply slowly be wiped out by lack of births.
