Interesting historical note: The Muslims started invading India (which used to obviously be Pakistan, Bangladesh, Kashmir etc) around 1000AD or thereabouts, and by 1400 had control over much of India (They never really got the southern part) and ALL the Muslims in India and Pakistan today (except for a very few) are the descendents of Indian Hindus who were FORCED to convert by the scimitar, high taxes, and other pressures. NONE were converted by reason, argument or superior idealogy. They looted, pillaged, raped, and murdered their way across the subcontinent for hundreds of years. And look at the legacy - hatred and poverty.
And all the Muslims in the middle east and most of North Africa were once Christians. Add to that the Muslims in the Balkans who used to be Christian and most of Turkey, also converted by violence and jaziya.
We in the America have never really dealt with the horror of islam until recent years. I hope we do not go down the path of "accomodation" that Western Europe, the Orthodox and Catholic churches have done. If we do, our children and grandchildren will witness even worse horrors than we see today.
