Save the World from islam

I have been dialoguing with muslims in Internet forums over the past two decades of my life; answering their many questions about the Holy Bible and the God of the Holy Bible, who is in fact the One True God that anyone can know personally. In the process, I have questions about islam. Questions, like if islam is a lawful religion, why does it have death penalties for anyone who wants to leave it? When the Holy Bible is the most thoroughly researched and verified literature on earth, the very foundations of our laws, such as Do Not Murder, why do islamic nations ban it? If muslims are worshipping the same Eternal Creator as those who know Him personally, those who understand the Holy Bible is telling us all the Truth, not just because it is compatible with reality and the facts of history, but because we have met the Risen Lord Jesus Christ Himself, and He has given us His Holy Spirit, whereby we know Him personally as our Heavenly Father (Romans 8:9-15, Acts 10:34-43, Acts 4:12, Acts 1:8-2:38,39, John 14:6-26) why have the extremists murdered and persecuted all other people throughout history to this very day? If islam is lawful, why aren't the islamic nations arresting the violent terrorists' organizations? if islam is a lawful, protected religion, why do they want to change our laws, that ensures everyone the right to worship our Eternal Creator according to their own God-given conscience? I suppose I'm not just asking these questions to muslims, but to all the world? Our Eternal Creator gives us all life, liberty and every good thing, that is the God of the Holy Bible, who commands us all to Love Him and each other. To never do anything evil to another person. This is the only way to live together peacefully. He simply tells us all the Truth. That is the God of the Holy and the One True God whom we know in the English language, as our Lord Jesus Christ. He tells us He is the One True God (John 5:39,40, John 14:6-9-26, 1Jn 5:20, Col 1:15-19, Jn 20:26-28) and anyone can verify that fact for themselves. So, I'm asking everyone to take a look at reality, The Biblical worldview has founded and funded the greatest number of humanitarian charities on earth; so many that even search engines on Internet have trouble listing all the millions and millions of pages of them and yet islam has founded and funded the greatest number of violent terrorist organizations in the history of the world. If islam is a lawful religion, protected by our laws, why is this the case? I suppose I'm asking not just muslims, but the entire world these questions in this book.
