Here we have a perfect example of what the late (and greatly missed) Lawrence Auster called the Unprincipled Exception:
The Muslim hijab as a symbol of Western-style feminism? Could anything be more obviously absurd? Clearly, then, absurdity doesn’t matter here: this is nothing more than the grabbing of whatever is closest to hand and using it to bludgeon an opponent. It is like an angry housewife throwing the dishes.
Feminists: both you and Islam have a common enemy, namely the traditional culture of the West. Islam will, of course, gladly help you destroy it.
But do you really imagine that once you have leveled and pulverized Western masculinity and femininity — and by doing so, have brought down the twin pillars of your civilization — you will then make agreeable terms with Islam?
