AJJ, you said, "just like Christianity." That's not true. The truth-claims of Islam, Christianity, and atheism are all very different and, in fact, diametrically opposed to each other. You're making false assertions that aren't true showing that you've never seriously studied these worldviews.
And from a Christian perspective (and you're on a Christian website), understand that where Mohammad was just a mortal man who died after creating a false religious system, J
esus Christ is the living incarnation of God restoring fallen creation back to the Creator. So if every Christian dropped dead tomorrow; Christianity would continue to exist in heaven and ultimately back on earth for the simple reason that Jesus Christ is alive, is God, and wills it.
Furthermore, you're wrongly asserting that what people believe has no effect on their behavior. Of course it does and the aggregate of scholarly social science studies on the topic clearly show that it does. I strongly urge you to take a sociology 101 course and learn about how it does.
Which brings us to Islam is evil because it's a violent false religious system that advocates and extends eternal rewards for engaging in genocide and slavery (including the taking of females as sex slaves and the castration of male slaves) which historically the followers of Islam obeyed (behavior follows belief) as Islam is all about 'submission' to the will of Allah.
Educate yourself. Read books. Read about the negation of India in which Muslims murdered 80 million Hindus. Read about the 150 million Africans they enslaved and compare that with the 388 thousand brought to the U.S.. Read about the 29 million Africans they enslaved and transported to the Middle East castrating 80% of the males in the process. Read about the million Europeans they kidnapped off the coasts of Europe during the Atlantic Slave Trade. Read about their relentless invasions that sparked the Crusades. Read about their invasion of Europe and burgeoning white slave trade they established and the severe oppression they implemented upon Europe's peoples. Etc... I have a library of history books from the world's greatest historians and they all say the same thing. Try some modern authors even. Read anything by Dr. Rodney Stark, Dr. Thomas Madden, etc... to get started.
Endless Jihad is advocated by the religious texts which comprise Islam until the entire world is submitted to the false worldview and violence, enslavement, forced conversion, etc... are all legitimized within the Islamic worldview to accomplish this goal. And I don't know where you got the idea that texts advocating for evil are not evil by themselves. They are.
Christianity, on the other hand, teaches the exact opposite. Christianity IS a religion of peace. This is true, whether or not professing Christians (who may not even be genuine Christians) violate the religious teaching they claim to hold to. Understand that when a Muslim engages in violence and enslavement to further Islam, they are following Islam and expecting to be rewarded for doing so. When a professing Christian does it, they are violating the religious teaching they claim to hold and expecting to be punished. Foundationally different.
And don't make the ignorant mistake that so many young uneducated liberals do in wrongly confusing colonialism with Christianity. Just because they both start with the third letter of the alphabet doesn't make them the same thing. Colonialism is a political practice that every major civilization throughout human history engaged in at one point or another including Muslims AND atheists (see 20th century state atheism for more information on that and while you're at it research state atheist democide too).
And you want to know why crime is low in Islamic nations? Because they don't slap you on the wrist: they chop off your hand instead. As the Institute of Arabic and Islamic Studies states:.
"Islam’s philosophy with respect to the spread of misconduct is embedded in... severe penalty. The severity of punishment of a Muslim serves as a giant deterrent to committing a crime. Because of the severity of punishment, the majority of people would not commit the violation or even begin to think of following it through."
But look at Muslim polling:
Muslim Opinion Polls - Challenging the 'Tiny Minority of Extremists' Myth
^ You don't see anything like this in the liberal democracies of Western Civilization.
And as for Christian denominations, you're obviously unfamiliar with the topic. First, the vast majority of Christian denominations adhere to the essentials of Christian epistemology and are genuinely Christian. Furthermore, these historically normalize to just a few parent roots. Most of their differences within these parent roots are minor and all surround non-essentials. As for the rest, since they not align with the essentials of Christian epistemology they are not genuinely Christian. These comprise the cults.
But you're making even yet another false assertion in stating there are thousands of forms of Islam. There's less than fifty. Less than fifty is not thousands. And, unlike the vast majority of Christian charities, those Muslim charities you're discussing are focused on helping other Muslims. This gets back to the enormous difference in status between a Muslim and a kafir (e.g. non-Muslims) in Islam. Read this and educate yourself about why Muslim charities predominately don't exist to help non-Muslims:
Kafir - Political Islam
Still further, you're making ignorant assertions about science and Islam that you truly don't understand. Though I don't have the time to get into that lengthy topic with you tonight, read
'How the West Won The Neglected Story of the Triumph of Modernity' by Dr. Rodney Stark and correct your misunderstandings and ignorance which are extensive.
