No you didn't say SOME you made a sweeping generalisation.
Further, the point about your own insular world was because you said you had formed these opinions being from Southall, which actually if you are going to use this to make statements about all muslims shows your own insularity.
Your attempt to shout me down was when you said I was an outsider so I couldn't possibly know etc. I notice how you are changing your statements after the fact and seemingly changing your stance.
Yes some muslim people may have difficulties when they move here, many do not. Some Hindu people have problems when they move here, in fact the communities that I have experience with have some families that are fully integrated and others that are very insular and only socialise whith others from their community, and are trying to enforce behaviours and rules on children that are very old fashioned but would be how things were done in India 20-30 years ago.
I'll give you an example, lovely young woman of my aquintance has a British boyfriend, but couldn't possibly tell her parents because they would be shocked if she came home with a "gora" and they expect her to marry a nice Indian boy from within their community, there are all sorts of rules that she and her siblings have to follow, traditions and pressures which are totally out of keeping with the way Western children are raised. Her parents socialise almost completely within their own community, the grandparents who moved here in the 50s do speak English, but not well etc etc. This is true of many Hindu families within their community, which is not that far from the one you were raised in.
But see I didn't make a sweeping statement did I, you did, its a massive flaw in your argument and you made it based on your own prejudices.
So it doesn't count.
