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 way around this is to seed the concepts, values and understandings of Islam in to society by our human interactions. Only when they acknowledge the worth of the code by seeing it manifest only then will people accept them. It is convenient for people to accept the principles of Islam without them knowing that Islam mandates or prefers them.
If we see something that is contra-Islam then we need to show its damage to society rather than exhume rage over it being anti-Islamic. The latter will only encourage the mischievous folk to poke the wounds.
So I agree with you, but in addition to creating a welfare state we need to realise that welfare in its best form is Islam.
