I'm sorry, go r your negative experiences. I am a British born Muslim and I have had equally horrible experiences in the UK, telling me to go back to where I came from (erm.... that would be Scotland!) and that my son and I don't deserve to sit in first class when travelling...
I am a Muslim and while I don't cover up head to toe, I completely respect those who do.
I think people find it hard to get around the fact the fact that, just as everyone is entitled to show off as much flesh as they want, they are EQUALLY entitled to cover up as much as they want!! Oppression and punishment is NOT the reason behind EVERY woman who chooses to wear the niqab/hijab/burka!
My SIL both wear the niqab, while the other two don't. Please don't believe everything you read/see/hear in the media. There are some genuine cases of women being forced to cover up, but there are just as many (if not many many more) who CHOOSE to. They don't need people 'fighting' for them, because it is their CHOICE to cover up.
With regards to the word 'modest', I am sure if it was instead called 'covered' there would be just as much uproar 'are they saying we are uncovered?!' Etc etc
