As the number of converts to Islam grows around the world, little is more surprising than the fact that the vast majority of those converts are women – by some counts, as many as four times the number of women in the United States as men. And over and over, as if reciting dogma, these women offer the same bizarre explanation: Islam, they say, with its "modest" dress code, frees them from the "oppression" of Western society and a culture that judges women on their looks alone. It is, in fact, as if they have bought into the religion not for its precepts, but for its costumes.

Perhaps you could even believe their reasoning if most of these women actually dressed in full chador or burqa. But they don't. Rather, they simply cover their heads – and occasionally their bare necks – in hijabs, or headscarves, arguing – with flawed logic and misrepresentations of the principles supporting Western notions of equality and feminism – that even this is a sign of "liberation" as much as it is of their allegiance to a religion.

And evidently, more and more non-Muslims are buying it, especially as legal battles erupt in Europe -- and in some American cities -- over the right to wear a hijab in the public realm.

Latest among them, it seems, are the editors of the International Herald Tribune, who earlier this summer ran an op-ed by Ayesah Nusrat, a self-described "Indian Muslim," defending her decision to don a hijab at the age of 23. (What the editors evidently failed to notice was that the pious young author of the piece lifted all of her ideas and a reasonable portion of her words directly from a previously-published essay by a Canadian Muslim, Naheed Mustafa, which is widely available online,)

Poorly written, speckled with faulty grammar and plagiarized clauses, Nusrat's piece presents a downright bizarre depiction of Western media and public opinion (among other things, she describes Western feminism as being defined by "a skewed perception of women's equality as the right to bare our breasts in public"). Nonetheless, her commentary places in full view of a wide public one of the biggest obstacles we face in combating the growth of Islam in the West, and, even more, of political, aggressively Islamist Islam as it masquerades as a faith – and a doctrine – based on justice and equal rights, slinking its deceitful, theocratic destructiveness into the secular humanism of the West.

And it is exactly that deceit which makes it all so dangerous, especially to young women struggling with their own body image and sexuality: what easier escape, what simpler coping mechanism, than to throw a sheet over your head before heading out in public, and convince yourself that no one either sees what you look like underneath, or cares? (Indeed, Dutch psychiatrist Carla Rus, who works closely with young Muslim women – including converts – notes that the ease of dress and discomfort with cultural emphases on appearance is behind much of the conversion of non-Muslims to Islam, and contributes to the radicalization of Muslim women in Western countries.)

But Islam is not about garments, any more than a hijab actually covers anything but a woman's hair. In fact, to the contrary, a hijab-wearing woman in the West attracts attention to herself merely by the fact of the scarf itself, and to the political statement it really represents: "I am not-you. I am Muslim. I am other, and I reject what is not me." It pronounces the "us" of "us and them" in a gesture of arrogance and isolationism, while ignoring the greater truth of any faith: that it exists in your heart and in your behavior, and no more.

Yet ironically, the women who place Islam in an article of clothing, who choose the so-called "modesty" of Islamic dress, the women one often sees covering their heads, parade along the streets of American and European cities in skin-tight turtlenecks and leggings, the lines of their lace undergarments visible beneath. Or there was the headscarved Dutch-Turkish woman I saw once who, in the jubilant post-game revelry of a soccer match victory pulled down her pants and shoved her cotton-pantied derriere out a car window in The Hague.

"Does that seem normal to you?" I asked an Iraqi friend of mine, who had herself recently stopped wearing a hijab.

"Absolutely," she replied.

Nonetheless, the rampant spread of propaganda like the Herald Tribune piece continues to serve the aims of missionaries for Islam and to falsify the truth of its misogyny not only for women, but for a larger public easily persuaded to tolerate the intolerance of its doctrine. (It is not, after all, the hijab that makes these women free, but the secular, Enlightenment values of the West; where else, after all, would they have the liberty to choose whether or not to wear one – or, for that matter, to convert to Islam, or to leave it? Where else, too, could a woman wearing a hijab stick her naked behind out in public view?)

The truth is that the decision to do anything at all – pray, tithe, fast, or dress – in abeyance to religion is anything but a gesture of "liberation." Liberation, rather, is what you get when you refuse to allow such gestures to define your worth - -either to society, yourself, or our god.

Indeed, hijabs – those, that is, worn for allegedly religious, rather than political reasons – declare a submission to religious mandate (or rather, the belief in one: in truth, the Koran does not call for women to cover their hair, or even their faces and bodies). Nor, either, does it serve to desexualize women, as the high rate of rape in Muslim majority countries makes abundantly obvious. What it does do, however – and what burqas and nikabs especially do -- is dehumanize them, creating faceless beings, property to be sold into marriage, beaten, or battered to death with the pelting of a thousand stones against their heads.

Consequently, the persistent misperceptions, the insistent protests mischaracterizing this symbol of religious and political subservience, these dishonest declarations about sexuality and freedom, echo beyond Nesrat's words; they spread through the willingness of a misguided media and naïve public to other young women at risk of becoming similarly misled. And if we fail now to confront – and combat – such misapprehensions and distortions with the unveiled and naked truth, we will have only ourselves to blame for what becomes of them.
