If living under Islam is so wonderful?

If living under Islam is so wonderful as in Egypt ,Afghanistan,Pakistan,Saudi Arabia etc why do three quarters of the Islamic worlds population want to go and live in secular states like Europe ,United States,Canada even bloody Turkey for christ sake (sorry!)Best thing to do would be as in the old Soviet Union ban that religion sh*t including the christianity crap and drag the world kickin and screamin into the 21st century and forget about imaginary bloody friends that do not nor ever have existed.
