Heretical ideas propose the extinction of Islam, not a reformation.

In Ayaan Hirsi Ali's new book, she states:

"For more than thirteen years now, I have been making a simple argument in response to such acts of terrorism. My argument is that it is foolish to insist, as our leaders habitually do, that the violent acts of radical Islamists can be divorced from the religious ideals that inspire them. Instead we must acknowledge that they are driven by a political ideology, an ideology embedded in Islam itself, in the holy book of the Qur’an as well as the life and teachings of the Prophet Muhammad contained in the hadith.

Let me make my point in the simplest possible terms: Islam is not a religion of peace. For expressing the idea that Islamic violence is rooted not in social, economic, or political conditions—or even in theological error—but rather in the foundational texts of Islam itself, I have been denounced as a bigot and an “Islamophobe.” I have been silenced, shunned, and shamed. In effect, I have been deemed to be a heretic, not just by Muslims—for whom I am already an apostate—but by some Western liberals as well, whose multicultural sensibilities are offended by such “insensitive” pronouncements."

Her points are valid but her conclusion isn't. It may be that Islam needs to change and a reformation may be needed.  But to do away with Islam entirely removes humanity from the dangers of radical extremism.  Society would do better to ban the practice entirely than to accept a reformed Islam.  She does all this work and stops short of the reasoned conclusion.
