I'm perfectly willing.
Named changed for this, don't want it linked to my other posts.
The area I'm talking about it an Asian/Muslim (predominantly Pakistani) area called Everton in Leicester. I lived there for two months in 2011. I'm a white woman, was 21 at the time.
Well I guess it depends how one describes a 'no go', right? True, I wasn't beaten up, raped or killed. But.
I was spat at, sneered at, called a whore, a slag, a slut various times in the middle of the day, just going about my business. Pushed by a woman in a supermarket for daring to 'look at her husband' (I was 21, he was in his 70s, I certainly didn't 'look' at him). Asked 'how much per hour' in the street. Propositioned in various (unpleasant) terms. I was young and a bit naive, so when I arrived, an Asian guy helped me carry my bags into the house. Next thing I knew (was told by a neighbor) I was 'fucking him' and all the neighborhood apparently. Had my underwear stolen off a garden line where it was drying. That's not all, but enough.
Not that it matters at all, but for the sake of the argument, I wasn't wearing any sort of provocative/revealing clothing. I was a student, usually in skinny jeans, tshirt and converse. Asian girls/women weren't treated this way. I was. Why?
Obviously, I moved out of there as quickly as I could.
Were all the people there like that? Of course not. But many women were obviously hostile and many men were predatory.
Anyway, that's my experience of a 'no go' area. 'No go' or not, I certainly won't be rushing to return. I live in Wales now, in a small market town. I can wear whatever I want and go about at all times, and I'm not routinely called a whore or spat at just for existing, being white and not covering up head to toe. Funny that.
Another (unrelated) thing. What stroke me as funny is this (a couple of examples, there were more).
One guy. 26 at the time. Pakistani. Arranged marriage in his own country, brought his wife here, already had 3 children, 4th on the way. She didn't speak English and didn't work, he worked at the fast food chain. How did they support themselves? Doesn't take a genius to guess.
Another one (similar age), wasn't married at the time. Planned to go back to his country asap to do so. Wanted 'a traditional girl' and 'a big family'. He worked at the supermarket.
And more.
