There are places where you can't wear hoodies, certainly motorcycle helmets are totally out in many places. And (again being honest) the association that people make with only the eyes showing is a balaclava helmet which has a very specific and very strong connotation in UK society. I know it's not very right-on to say it, but in UK society, generally, the only time you would see someone on the high street or in a shop with only their eyes showing was if they were about to hold you up with a shotgun, or blow you up. And I know it was a few decades ago, but it's in my living memory, and I think when people say they are very uncomfortable with people only having their eyes showing, there is a very strong cultural reason why, in recent history.
And I know it's not PC but if we're worrying about cultural sensitivity then that aspect should be considered as well, I think?
FWIW I agree with others that the "security" line in the UK is a cover-up for other reasons (such as all the ones mentioned above).
I also think that dreaming is right in that over time as (hopefully) different communities become wealthier and more integrated, so full veil wearing will drop off.
I don't know why I get on such a rant about this. I just know that when I see a fully veiled woman, it freaks me out. Culture / feminism / who knows. But I can't pretend I'm OK with it, I'm just really not.
Incidentally doesn't being fully veiled (cultural) come with a whole other bunch of expectations around female behaviour (cultural)? There was a thread on here and I said that I wouldn't like it if where I lived, everyone wore a full veil as how would anyone recognise people they knew / were acquainted with when out and about and stop for a chat. The answer was, why would anyone want to talk to people on the street, the thing to do is socialise at home with people you have invited around. It's just a totally different mind-set to how most people in the UK are, I think. I take it for granted going out and about and saying hello to people I vaguely recognise, and smiling at the person who sells me some stuff in a shop, and bumping into someone I worked with 10 years ago and that sort of thing. It really is just a totally different way of living.
