I hope you don't call yourself a feminist while talking about the decisions muslim women make for themselves regarding their religious identity and expression without knowing and speaking to one yourself.
And this is for everyone talking about how our religious belief is oppressing us: we have thought long and hard about our beliefs. We thought long and hard about the meaning of our life. We have thought long and hard about what we want to do in our life. We weighed the risks and rewards and continuously do so from the moment we wake up to the moment we sleep. Each of us came into the conclusion that she deems is the right way to live, and is concerning us and each of us alone. We do not need white warriors to show us the way. We do not need your opinion of how we have internalized oppression and how we don't know better because we live through oppression day and night, inside and outside, that we recognize it in all its hideous forms. We do not have a safe space in this world, because whether we wear the niqab, the hijab or none, the sole fact that we are women, muslims and sometimes brown or black means we are not worth safety and recognition in most parts of the world (seriously, is there anywhere in this world that accepts someone like me?). And if we happen to be queer, than we are dead. Our safe space is our religion. We do not need the white colonist rhetoric of saving us from ourselves, we have already done that ourselves. Only ensure us physical and financial safety, thank you very much.
If you have no power to do that, shut up and leave us fight the good fight ourselves.
Your post offers a solid rebuttal against the argument of "its oppressive" though frankly I think you underestimate the impact of internalized oppression over years of being told that the niqab is required. But I digress - that isn't what this post is about. Other posts have covered my stance on that well enough.
Unfortunately, this goes beyond just women, because women do not exist within a vacuum. They, like everyone else, are part of a shared society. To me it comes down to, do we want a society where certain members - specifically women - cannot be identified at all? Is that a standard we are collectively ok with? I'm not. It isn't right.
GAF likes to peddle the idea that "You can wear whatever you want without restrictions and no one can judge or tell you otherwise." This is naive nonsense. We are social creatures and we have social constructs, and they do matter. Certainly, sometimes this goes too far (like tattoos, which can be seen as counter-culture even though they are increasingly more mainstream), but Id say there is a reasonable limit and the niqab is really far beyond it. Just as how you don't see people walking around naked, you shouldn't see people covered from head to toe, with the exception of halloween or going to comic-con. The fact is, everything we are allowed to do in our society has reasonable limits.
I already know that someone will write a counter to the above argument, saying that women in our own society used to be required to cover up, and it was only over time that women pushed boundaries - making other people uncomfortable in the process. So why was that ok yet here I am arguing against a niqab? Again it comes down to reasonable boundaries. The hijab is fine - if people are uncomfortable by that then too bad. But the niqab takes things to the extreme, and thats the problem. As with many things in life, taking things to extremes is wrong.
So, I'm glad the niqab doesn't make you feel oppressed. But it does make me, and others, uncomfortable, and I think in this case our discomfort is understandable. And since we exist within a shared space, yes, I think that matters. Countries do need to bend a little to the cultures of immigrants. But immigrants also need to bend to the cultures of the countries they are moving to. This is an area I do not think western societies should be giving an inch of ground on. Modesty is fine, absurdity is not.
