“Is Islam at war with us/the world?”
It is really Saudi Arabia, trying to covertly conquer the world, for their extreme version of Islam.
Of the four main Sunni schools of interpreting islam (fiqh), the Saudi Government adopted the smallest and most extreme - the Hanbali school. From this extreme approach, comes the Wahbbis, Salafists, Takfiris, ISIS, al Queda, Boko Haram, the Muslim Brotherhood - all the Sunni murderers plaguing the world today. Saudi Arabia is the source, the funder, and the safe haven of this scourge on humanity.
What makes the Hanbali school extreme?
1. They absolutely, explicitly reject the use of reason or judgement interpreting scripture. They adhere to a doctrine of Athari - only literal reading is allowed, either to determine law (sharia), or to theologically understand God and the divine law. Their view is that human reasoning and logic are wholly inadequate, and unreliable - more likely to error than not. They are the worst sort of closed-minded Fundamentalists.
2. They accept only text from the quran and the example/opinions (hadith) of the original group of muslims (muhammad and his companions). These were people totally dedicated to violent conquest and backstabbing each other for power - not cultivating their characters or perfecting their morality. No Old or New Testament is accepted, no scientific fact, and no philosophizing or moral analysis of any sort. They base everything on a fundamentally corrupt source.
3. They (arbitrarily) use a doctrine of pre-emption, where things that were said or done later, supersedes whatever came earlier - even if the earlier statements were pronounced by muhammad as direct revelation from God. God changed his mind several times apparently, but stopped doing so a few decades after muhammad’s death. This is a bad rule, because early in his career, muhammad lacked the power to force his will, and made many statements about tolerating others, or “there will be no compulsion in religion”, or such. All of that is contradicted by his increasingly brutal and totalitarian policies as he gained power - until he finally got to “I have been ordered (by Allah) to fight against all people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah’s Apostle”. The doctrine of pre-emption, coupled with the literal reading of only a limited set of documents, negates the option of tolerance and results in a requirement for world conquest.
If people are afraid of contesting islam on its merits, or believe that such an approach would not succeed, they could instead undermine or outlaw the Hanbali/Wahabbi/Salafi/Takfiri teachings, that preach terrible hate, oppression and incite endless war.
That is what has been recommended by folks like the King of Jordan, and the President of Egypt. It would require censoring the Saudi funded imams, mosques, media outlets, and activist organizations, as well as neutralizing their terrorist arms.
