I get where you're coming from, and want to give you props for the reasoned, measured response. I want to point out, though, that part of the issue here is the growth of secularism in the west. We can talk about this some more if you disagree, but that is itself an ideology, not the rejection of one, except it's anchored on subjectivity ("what's best for society" doesn't have any concrete definition in itself), and is vulnerable to influence from a structured ideology. The growth of Islam in the west goes hand in hand with the idea that all ideologies that aren't "harmful" are equally valid, despite the fact that part of Islamic doctrine permits adherents to deceive others if done for the promotion of Islam itself. (Not saying that's your mindset in particular, but that's what we're observing in general.) And as we also see with proponents of socialism or communism, people can willfully disregard historical evidence that some ideologies are demonstrably harmful long-term, as long as you can convince enough people that those ideologies just weren't implemented "the right way."
If we tell people not to do something, they need to have some framework to fall on to determine why beyond "look at what happened last time," because we're seeing that's not enough.
