Yes, according to the World Christian Database, Islam is the fastest growing religion in the world over the period of 2000-2005: http://en.wikipedia.org/wiki/Claims_to_be_the_fastest-growing_religion In terms of the current breakdown of numbers: 1) Christianity 2.1 billion 2) Islam 1.5 billion http://www.adherents.com/Religions_By_Adherents.html Obviously then, the world already has more Muslims than Catholics: http://www.catholic.org/international/international_story.php?id=27384 Here is a good map illustrating the distribution of Christianity vs Islam over the world: http://en.wikipedia.org/wiki/File:Christ_Islam.png Interestingly, there are 4 million Muslims in Germany (4% of population) but only 2.5 million Muslims in the whole of Lebanon (60% of population). There are also nearly 2.5 million Muslims in the US (0.8% of population) http://en.wikipedia.org/wiki/Islam_by_country By 2050, there is a good chance that Islam will be the world's most dominant religion primarily due to higher birth rates.
Yeah, their birth rate is high enough that they can afford to have suicide bombers. Unfortunately this hasn't hindered their ethnic cleansing efforts in Europe.
Please give a link to support your claims so we know you are not just pulling those numbers out of your ass and giving us ignorant uneducated propaganda.
