As I said up thread, I'm from a multi-ethnic, multi-heritage background, as is my DH. I've also lived and worked in other countries, including in the ME.
I personally believe we all, in Britain, see "culture" through a very strange lens. My experience has taught me that "culture" is largely geography (as is religious expression). People in certain places do certain things because those things make sense where they live.
Take Bedouin facial veiling: that makes total sense if you are female and live in either the Arabian or North African desert. In fact, no matter who you are, you are kinda daft if you don't do it if you find yourself in the desert because it stops your nose burning off.
The saying "When in Rome ... " is sensible, but not because one way of doing things is more "superior" to another, but because a particular way of doing things in one particular area tends to be the best way of doing that thing.
Not eating a big, cooked breakfast is a sensible idea if you live in a hot country, as is not drinking huge amount of beer -- which is why Southern Italians, Greeks and Arabs drink coffee for breakfast and tend to consume more spirits (hence the Gulf obsession with whisky).
No joke, almost every cultural thing you can think of has its roots in a specific geography. Accents, for example, tend to reflect the landscape of an area: the more hilly, the more singsong -- which resulted, for example, in Welsh male voice choirs. What you build, and how you build it, and what you build it with also creates culture and how a human thinks and perceives the world around them: dry stone walls don't tend to last in hot countries, for example.
And this does affect all manner of expression. The Christian Church would not have survived in England, Wales and Scotland if it had mandated praying on the floor. It would have just been too damn cold. By contrast, cool places to reflect/pray work in hot countries, hence the reverse situation with Islam.
Indeed, I'm pretty convinced that England, Wales and Scotland have historically over-produced in terms of literature because the climate (cool evenings and endless rain) meant that people stayed indoors and where just in the right atmosphere to start jotting down stories.
What the issue is now is that we have huge numbers of people bringing their way of doing things from one place to another very different place, and those ways of doing things don't work -- and it is causing problems.
But because we seem to view "culture" as some sort of synonym for race, ethnicity or creed, no one is actually saying "Mate, that aint going to work here because #practical reasons."
I mean let's be blunt here. The reason why generally we have different attitudes to women in public space in this country is because, unless you are fairly wealthy, most of the females in a family will have to work outside the home at some point in their lives, which means they need to be safe in public space and free from harassment. For the majority of British families, females working outside the home is a matter of financial survival. It is today; it was in the 1950s; it was in the 1850s.
It's not that women are in public space because our culture is somehow "superior" per se, but because that is a necessity for how most families survive in Britain. If you have a family where you have one adult male and five adult females, and none of those women can go out to work because of the sheer harassment and aggression on the streets, your family is going to face poverty.
In short, harassing women and girls in public = creating spaces for poverty and deprivation to take root.
I think we need to start talking about "culture" in this practical way. It's not a clash of ideas or beliefs; it's about the way we do things in Britain to ensure the survival of our families, and making it clear that the way you ensure that survival in another very different place is not going to work here.
