ok i will answer it now after considering it more yes i believe it is unreasonable to want to live around those who have only similar values and lifestyles to me, although I believe lifestyles and values needs to be defined and made clearer in your question, as for people I can identify with, I find myself able to identify with people from all backgrounds, religions, cultures so I dont get that part of the question which is why I said "in part".
How does covering make my lifestyle Alien and nullify all the other things that I do which are not "alien to the UK of the 21st century"? and why am I seen as not part of the UK of the 21st century as I consider myself to be part of the UK of the 21st century, it is only others that tell me I am not?
Tell me what is my lifestyle? I get up in the morning take my kids to school, get involved in PTA am on the governors, organise charity events, fund raise, have coffee with my friends, go shopping, study, do community stuff, do some mumsnetting, do some facebooking, write on my blog, etc how is any of that alien just coz i cover? how is my whole lifestyle defined by what i wear?
My lifestyle is being a SAHM, so I dont see how that is irrelevant to your question, if it is not what you meant you need to define the concept of values and lifestyle which you are talking about, since my lifestyle is not different to sahms of other religions...
