Give a convincing explanation/answer to his question above. Is it a crime to refuse to follow blindly?

Someone I have know here since that he doesn't see to reason and is ready to do all he can spoil the pristine Islam that the prophet brought!

And I wonder what the argument is about.
It is not permissible to lie except in those cases listed which is an exception. And a Kuffar is a disbeliever in Islam. Christians are Kuffar because they disbelieved in the last prophet and they say Allah has son.
