Some people said that Islam would be reduced to its quarter size by the year 2020. But even the most conservative estimates suggest that Islam is growing. So if you can do your basic maths, you will know that about 1 Lakh muslims are added to Islam daily. Now someone said that they are only increasing in number because they are breeding like animals and no one is getting converted. So if no one is getting converted then what is your worry ? Have fun. :-) Or maybe you can control your own people running away to buddhism.
