It's not my opinion, it's an actual fact. do your research on Islam. As I already said, the so-called "peaceful" muslims are not even following the quaran, which is what Islam is based off of. The quaran is a discombobulated writing of a deranged man who was overcome by Satan in a desert cave.
What you just said regarding the Bible is sadly a common mistake as a result of taking history out of context. Those stories are from the Old Testament, when laws were different and sins were punishable by death. When Jesus died on the cross for the sins of the world, past, present, and future, the old laws were done away with, and now man has a way to be set free from our sins by the forgiveness of Jesus Christ.
Do not twist the Scriptures to fit your hate.
Any "Christians" in the past who have killed were not true Christians. True Christians are not some hokey religious group throwing tracts in people's faces and whacking them upside the head with a Bible, true Christians are just ordinary people who have hit rock bottom and gave their lives to Jesus because we realize we can't make it on our own. No one has the power to save their own soul, that is why we need Jesus.
Please do not fall for the lies the world shoves on you. Seek out the truth. Use your God-given intellect and think. Find the evidence for yourself, and you will see. You will never find true peace without the Lord.
