Religion is a poor excuse for some behaviour.
The French have it right, keep it in your own privacy or place of worship.
Just because X amount of people believe and act under the same 'religion' it is ok to act in whatever way may suit that religion.
If tomorrow I began my religion that said I could wear a mask everywhere, and carry my 12inch ceremonial machette in public, and it be against my religion to have handcuffs applied, would it be acceptable? No.
What difference does it make how many people have been brainwashed from birth, with whatever nonsense or faith based belief they have?
When elements of someones faith/belief goes against what is best for society as a whole, then it has no place.
I'm sure 90% of those that wear these outfits would be happy to show their face if needed (ie, petrol station example), but it's the 10% who won't and then complain and bitch that need a good slap

If you don't like it, then change your religion, or sod off. You can't help your race, colour or creed, but you CAN help what nonsense you may believe in, and if you are a tolerant person, accept that everyone has to be kept happy, NOT just you, and so you should do your bit to work together!
Gah. I'm all for anti-racism and equality in that regard (where it can be applied without being racist in itself), BUT, religion really boils my piss when it's used as an excuse to be a s**t!
