Islam is growing because of breeding like cockroaches (specifically inbreeding amongst cousin brother and sisters).
Islam in USA is 0.35% lesser than hinduism 0.45%. Moreover human index of Mulsim population is the lowest worldwide and it is a religion followed by the most backward and illiterate poeple living below poverty.
So if you remove 60% of poeple following islam who are below poverty (basically like animals) and if you remove their growth rate, Islam is nowhere and nothing. Majority converts are negroes and criminals in jails, no positive contribution to society except inbreeding.
