A group of decentralized institutions within the justice system of Roman Catholic Church were guilty of forced conversions during the infamous Inquisition. Protestant Christians were considered "heretics" and became suspect as well. Christianity, however, spread throughout the centuries because of the power of the Holy Spirit to convict one person at a time to turn away from their rebellion against God. No forced conversions were necessary.<quoted text>
Historically it's been Christians who are guilty of forced conversion. The Quran states;
The Qur'an states "Let there be no compulsion in the religion: Surely the Right Path is clearly distinct from the crooked path." (Al-Baqarah, 2:256)
You're an ignorant bigot and a complete idiot!
You should take that passage from the Qur'an to radical Muslims. Just don't expect to come back.
But you can walk into any Christian church anywhere in the world and feel safe and welcomed. Radical Muslims might blow you up or kill you in the Middle East, but the fact is Christians are still persecuted even today.
