I'm not sure why it's assumed that that's not happening. Does the OP speak Arabic, Farsi, Pashto, Somali, or any other language spoken by many Muslims so as to be able to visit their mosques, chat rooms, etc. and see what is being preached or taught in them?
I do speak at least some Arabic (not a native speaker by any means, but I know enough to get by in church where we use it a little bit even in America as a concession to the fact that we are still receiving immigrants from Egypt, Libya, and Sudan), and have spent many hours around native speakers who do exactly what our friend frienden thalord is suggesting by preaching Christ to them in various venues (since we are in America, where the prohibitions of living in an Islamic society do not apply, thank God). From what I have personally seen, I'm not willing to paint things in such a black and white fashion. For sure there are many Muslims and schools of Islamic thought that
do advocate violence (no doubt Salman Abedi belonged to or was influenced by those), but that doesn't mean that Muslims wouldn't struggle with it. The Qur'an does say "fighting is prescribed to you,
though you dislike it" (2:216; emphasis added), so even the Qur'an recognizes that most average Muslims aren't going to want to go out and hurt people. They must be cajoled into doing so by various means, which kinda helps to explain why so much of the Qur'an and other Islamic literature and thought emphasizes the superiority of Islam over other religions (as all other monotheistic religions also believe about themselves, but it's generally not coupled with a drive to fight others for not being whatever you are).
It would be a lie to claim that the Qur'an or Islam are entirely peaceful, but Muslims themselves are still human beings, of course, and so they can be reasoned with to the extent that any human being can be.
To hear certain Muslims talk about it, the problem is not that there is violence anywhere in their religion (full stop), but that the way it is preached in mosques is unbalanced and creates neurosis in the followers of the religion so that they act out of fear and against anything which seeks common ground among people in society.
The man in the video is Dhiyaa El Musawi. He is a Muslim from Bahrain talking about his own society, and I believe that the problem that he is talking about is also becoming the problem of many other societies in which Muslims live. But it's important to recognize that he's out there, and there are others like him who are pro-human rights and anti-backwardness. I remember after ISIS first arose in Iraq and started claiming the property of Christians in Mosul and elsewhere, there was a demonstration against that (I think it was in Baghdad, but it might've been somewhere further north; I honestly can't remember now) that was attended by some 200 Muslims who held up signs reading in Arabic "I am Christian" (with the letter nun highlighted, as that is what ISIS had spraypainted on Christian homes). Also Al Sistani or one of the other major Shiite clerics had issued a call to the entire nation that as ISIS was a threat to every Iraqi, all of Iraq should come together to fight them regardless of religion (that was answered by some Chaldean Catholics, who are the largest single group of Christians still remaining in the country). You might be tempted to say "Oh, so what...200 people out of how many?" or "Big deal; one guy", but that's not nothing. What is out there should be recognized and encouraged, lest people like this bomber guy overshadow everybody so that everyone in the West continues to think that nothing good can come out of the Middle East or North Africa. That would be a recipe for more conflict just as sure as anything.
