If you mock the idea that Muslims should actively denounce and fight against Islamic extremism . . .

. . . you're against President Obama on this:

We cannot turn against one another by letting this fight be defined as a war between America and Islam. That, too, is what groups like ISIL want. ISIL does not speak for Islam. They are thugs and killers. Part of a cult of death. And they account for a tiny fraction of a more than a billion Muslims around the world, including millions of patriotic Muslim-Americans who reject their hateful ideology.

Moreover, the vast majority of terrorist victims around the world are Muslim. If we're to succeed in defeating terrorism, we must enlist Muslim communities as some of our strongest allies rather than push them away through suspicion and hate.

That does not mean denying the fact that an extremist ideology has spread within some Muslim communities. It's a real problem that Muslims must confront without excuse.

Muslim leaders here and around the globe have to continue working with us to decisively and unequivocally reject the hateful ideology that groups like ISIL and Al Qaeda promote. To speak out against not just acts of violence, but also those interpretations of Islam that are incompatible with the values of religious tolerance, mutual respect, and human dignity.

But just as it is the responsibility of Muslims around the world to root out misguided ideas that lead to radicalization, it is the responsibility of all Americans, of every faith, to reject discrimination.
