I know several women, through the work I have now retired from who wore burkhas.
They chose to wear them, there was no coersion, no grooming. These were highly educated, wonderful women who made a choice.
When I had known them for a few years, and had developed a close and friendly relationship, I did ask them why they wore them (i had seen them all without burkhas on numerous occasions in private).
They felt it was liberating. Simple as that.
They never had to worry about how they looked, just how they acted.
No concerns about how their hair looked, just what they had to say.
These women were the most loving, giving, highly educated and wonderful people. To her them being denigrated as nothing more than 'letter boxes' disgusts me.
