alex, i think you have to accept that many muslims interpret the verse in the Quran to mean they have to cover there hair/face and they also follow hadith, not only QUran.
sports, are you seriously suggesting that people born and bred here do not contribute to the shaping of the culture?
when people started wearing punk clothing, was that wrong as they werent having the courtesy to conform to culture?
when people in the 70s started wearing mini skirts was that wrong as they werent having the courtesy to conform to culture?
these women are not some kind of foreigners, they are British, most of them born and raised here.
if you were born in a culture in which it was the norm to cover your face, but you didnt want to, then would you conform, or as part of the culture would you think it was fine if you didnt and there was no laws against it?
if there were laws against it and you felt strongly, would you then fight against it?
