Ahem. I live in a northern former mill town. In the 1950's we invited people from Pakistan to work in our cotton mills because locals no longer wanted this work, there were better alternatives available.
We now have a fairly large population of people, descendants or relatives of those early settlers. Thirty years ago, it was rare to see any of the Pakistani Muslim heritage people wearing traditional clothes. These days, its very common, especially around religious holidays when the men wear flowing robes. We have a growing population of women who choose to wear the long black gowns, including head and face covering. I haven't researched this but it followed the anti Muslim feelings after 9/11 and other terrorism. My feeling is its political, it's a statement of solidarity with faith and belief systems. It's also in opposition to the growing number of young white British people who strip off to tiny shorts and tops (girls) and no tops, boys at any sign of warm weather.
We still manage to live in harmony. We shop in each others specialised shops, where people can be heard chatting, especially about children. "oh isn't your baby lovely, how old?" I've never seen any burka dressed woman respond with anything other than friendliness to that kind of comment.
I can't say I'm a fan of the burka. I've spent all my adult life working for equality, against the oppression of women. It's obvious that in some cultures women face more oppression than in others. I can't agree though, that every woman who chooses to cover is doing so because they're frightened of the men in their family. Some, yes but not all. I don't like to see small girls covering their hair either. But, I don't like to see small girls being given pole dancing parties as occasionally happens in the white British population.
