My choice was no...surprise surprise.
1. By definition, by "muslim" do you mean everyone born a Muslim...or do you mean every practicing Muslim?
2. Before Islam, the same Ishmaelites were pagan savages. Now they justify their savagry in Gd's name.
3. What will make the world a better place isn't necessarily a lack of Muslims... What makes the world a better place is the lack of jealousy and envy and evil behavior...whether it be a Muslim, a Jew, a Christian, a Hindu, A white person, a black person, an orange person, a pink person, a blue person, a Martian, or a Sri Lankan etc etc etc.
So even without Muslims, you don't solve the problem of evil. Where one evil group is eliminated, another one will arise against us. Better remove the ideologies which create evil, jealous, envious people!
