No law can ban a belief, only public expression thereof, or harmful actions based upon it. Thus, while there is no point in legally banning Islam or Judaism, because it simply wouldn't work. Banning the public practice of eithr or both religions is poddible, but an act ot totalitarianism. However, the criminalisation of both male and female genital mutilation (circumcision) is proper to a reasonable democratic government, since the practice is known to be harmful, and if carried out on an infant incapable of informed consent, constitutes assault and physical abuse, IMO.

As to holding and expressing opinions offensive to others, we all do that. I find the adulation poured upon professional sportspeople offensive to a degree, but I have to live with it.
