Islam will be history in a very near future. They need not be killed by non-islamists. Every muslim country is in the grip of anarchy. The Sunni-Shia and other sectarian strife will ensure that brother will kill brother and clean the world of islam.
Each and every Muslim, who believes in harmoney among peoples, who believes in love and compassion, in peaceful co-existence, will convert to Baha'ism. As said earlier, the fanatics will kill each other. Kaput.
