How would you know if the non-hijabis have/havent got religious convictions from the heart? Last time i checked only Allah was Omniscient.
In order to respond to the above we need to define and operationalise our concepts;
let us confine ourselves to the one you used above:
Religion; a dogma that purports to have a devine approach to how we lead lives. There are several religions, offsprings i.e they come in different shapes but appear to have a monopoly on what will happen after death.
Islam; submission; social justice religion at the onset but it is imaged have been tarnished by fanatics (wahabis who blend it with arabic culture). At the heart of islam is the notion that everything you do is between you and your Allah. But, there is a collective culture among its followers.
If only Allah is omniscient/omnipotent (which I agree is what the key message of islam) why do we have people who act as Allah's soldiers? Allah does not need soldiers.
The message of my thread is simple; our society today cares less about religious convictions and more about peer pressures resulting in double standardism. The dress code is not islamic
