Islam is the fastest growing is very inaccurate, if implied worldwide. It may be fastest growing in US, where many criminals in prison and violent people as reported are turning to Islam for acceptance of their nature, after being a society misfits. So please don't impose statistics of a tolearant society as US (where also statistics is only available). If only Middle East was a tolerant society as the US; then other religions would have been very prominenet there; i.e. the Middle East. But unfortunately, Muslim countries just don't tolerate co-existense of other religions. So please don't equate. Please pray that Islam does becomes smaller and smaller year by year, so that the world will have more PEACE; LOVE; DEVELOPMENT; Less terrorists; jihadis etc..., for the welfare and development of the entire human beings species without any discrimination towards nationality/race/religion etc....
