I don't think it's islamophobic to realise this dress is actually cultural and not actually something that the religion dictates you do.
All that the book says is dress modestly. That in itself is an interpretation.
The reason women dress like this in these cultures from many centuries ago, is because of men and their roving eyes. If men could control themselves, women wouldn't have had to over the years, dress like this. It's all to protect from the male gaze which is the problem that I have with it. It is now sold as it's a choice thing and I am sure many believe it is. But if they didn't what would their families say about it?
I have no problems with the ladies wearing them and not saying they are coerced every time of course. But how it all started was because of men let's not pretend it didn't. You only have to look at men these days in all cultures and their attitude to what a woman is wearing and did she deserve it because of what she wore, it's sick and it's on the man not the woman.
Quite often in my city, I will see the man in western wear and the lady in full regalia. That in itself is incredibly sexist to me.
My friend is from a Muslim family. They are quite relaxed in a lot of ways, her mum is actually worse in her views, being from an African muslim country and her dad is a bit more relaxed having being born here. My friend has tattoos on her legs they have no idea as she isn't allowed to show her legs at home. They don't know she drinks, they don't know she actually doesn't believe in Islam at all. She has a white boyfriend and they know about him. She will moving in with him in the next year. She even eats bacon! It has been eye opening for me, her experiences.
She is like 30 and has to hide all this stuff and how she dresses when she isn't at home because of double standards for women.
I do agree if you want to wear regalia then do it if you want to. But it is not islamaphobic to understand the misogyny behind it.
