Re: Blasphemy law
No one agrees with everything about a system, that's why in a democracy, unlike in Islam, people can make changes. Freedom of speech and thought is cherised.
Musilms are welcome to practice their faith as they please, but the foundations and ideals on which western democracies were built are in deep/systematic conflict with these ideals. As you say, USResident, if they don't agree with the* basic* ideals of a society, they should leave the state and go to one which coincides with their beliefs or live under the privileges that the system provides.
Why shouldn't these radical ideals be "deemed dangerous to the national security and its existence and ideology or treason" as you say is the case when those who disagree with the fundamentals of an (imaginary) Islamic state are?
We are talking about advocting fundamental changes to societies where Islam has never had any influence -- changing centuries of established laws and culture with a religion and culture that not only has been proven to be unsuccessful, but imposes religious restrictions in a secular society.
