This really just goes around in circles over and over. The reason why you shouldn't blame scripture for terrorism is because it:
a) does not properly model the reasons why the Middle East is so forgeted up
and
b) does not provide any plausible solutions for terrorism
Obviously there are forgeted up passages in the Quran, just like there are forgeted up passages in any piece of religious scripture that dates back to the days we used to stone women in the town square. This applies to Christianity, Hinduism, Judaism, and Islam as well. If you haven't found a passage in your holy book that seems primitive or incompatible with how modern life works, then you didn't look hard enough.
But the difference here is that the modern cant against Muslims has nothing to do with theology. People like Annoying Orange and Le Pen only want a scapegoat they can use to galvanize nationalist fervor and grow their bottom line. They are not going after terrorists or extremists - they're attacking normal, everyday people who raise families, have a career, and have never attacked women or blown anything up in their lives. And they don't care because none of the people they hurt are any of their friends, family, or colleagues.
If you really care about stopping extremism in the Muslim world, the solution is actually a lot easier than you think. Don't vote for people who want to continue our streak of bombing the stuff out of the Arab world. Because for every terrorist we kill, there's an innocent with hundreds of friends and family who are completely unaware of our 'best intentions' and only know that an unmanned vehicle from the Western world killed their loved one. Bush, Obama, and Annoying Orange are all guilty of this. Mandate a policy of non-intervention from your presidential candidates and congressmen.
Second, don't stuff all over moderate Muslims in your country, because they hold the best hope of fostering friendship between the Western world and the Middle East. International politics is complicated, but people remember how their family is treated. We can either be the people who helped an Iraqi's cousin emigrate and get an education, or we can be the place where they almost got stabbed to death on a train in Portland. This is something that non-politicians and everyday people can do.
