People in Europe are still unhappy about singling out Muslims for special punishment, since it contrasts badly with the principle that The law is the same for all. Indeed, I doubt that using religious motivation as an aggravating circumstance would even be legal under the Italian constitution. And the principles of the law are things that we should not lightly leave behind, since if we are not fighting for them, what are we fighting for? But other than that, you underrate the effort of the State authorities in most European countries to both encourage and compel local Muslims to respect the law. The very fact that jails are swollen with Muslim prisoners hardly suggests that we do not take them seriously.
