You flaunt the lowest point in American ethical standing - the Patriot Act - as an actual defence? If there was ever a reason to rise up against this very anti-American law, this is it.
Thumping the constitution goes out the window when you have draconian detention laws like the Patriot Act. I mean if something being a rule was sufficient, then Saudi Beheadings are laws too, whipping and caning for immorality are laws too, blasphemy acts are laws too and if you would recall not too long ago, Slavery was lawful too.
It's unacceptable to bow down to unacceptable laws. Great men have changed the course of great nations (including yours) by standing up to tyrannical laws. America was founded in dissent of the law of the unacceptable monarch. This woman's dissent was justified in the face of discriminatory laws and very American as discrimination traditionally, before the Patriot Act, was perceived unacceptable.
You're living in a fools paradise to think Muslims won't push back with all the discrimination against them. This is one but a small incident.
