After looking at the comments from Muslims in this articles it is very clear that their religion teaches to spread like dogs, follow violence and cruel talks. Since majority follow it without sense, we need not classify them as humans but to some separate low level species. Whether other religion survives them or not depends on how bad they are. So the more bad they are more fast they multiply. As it is Kaliyug, they will prosper. What ever they do, history will know that it never had great people whom all can appreciate.
