It may not always be the husbands. I've worked with some guys who have moved here and their attitude is they want their wives to feel free to adopt western dress etc. They come here because they don't support the oppression in their home countries, but it can be a little difficult to speak out without having a "visit" from the authorities. Don't forget that some of these women have been living in countries where it is illegal to expose skin etc. They've lived that way their entire lives, so making a change (if they want to) can be some what daunting. For some it may be a gradual process, for others they're out buying a "Wicked Weasel" as soon as they leave the airport. Perhaps what they were wearing at the water park was 'daring' for them.
aaaaand another thread goes wildly off the rails
