“That which does not kill us makes us stronger.” It was not Muhammad but the German philosopher Friedrich Nietzsche who said that, but for many Muslims living in the post-9/11 era, it may ring as true as one of the prophet’s teachings.

The decade since the Sept. 11 terrorist attacks has been tough for many Muslim Americans — from the anti-terror surveillance aimed at mosques, schools, organizations and individuals to the wave of hostility fanned by those who see their religion as fomenting hatred and violence.

After 10 years of struggle, the community is better positioned to defend its interests and more willing to reach out to the broader population.
