Re: Khawarij- open discussion
A state based on "religious doctrine" will alienate the people who do not beleive in that particular doctrine. A welfare state works for betterment of all citizens regardless of their doctrine.
The basis for a welfare state is to provide or subsidize products or services to that sector of people that cannot afford to fulfill their basic necessities such as sustenance and medical treatment.
An Islamic state does not differentiate the rights to such things based on religious doctrine meaning muslim in need of sustenance or medical treatment will not be given preference over a non-muslim with the same needs.
Even if the state is Islamic then all subjects of the state have equal rights. There is nothing in the Quran to the effect which says to discriminate with non-muslims when living under the Islamic state.
Even in a democratic state the rights of those minorities that get trampled by majority opinion face an equal bias or alienation against the ideology of the majority. In an Islamic state it just so happens the same democratic ideology is vested in Islam.
