You could start by disassociating yourselves from the evils in your holy book in which these more radical Muslims act upon and condemn them at a fundamental level instead of just ignoring them by saying "Islam is the Religion of Peace", "They don't follow the Quran" and acting like they don't exist. The problem is that non of you are willing to accept that the Quran is filled with violence and evil, you aren't willing accept those things are there and make a conscious effort to get rid of them and adapt to Western Culture, merely being oblivious to them is not enough.
