On Scremersford's experience.
Funny how different one's experiences can be re integration.
I live in Germany in a predominately Turkish area. The kindergarten my son went to was very international, but Turkish kids did form the majority. I spent time together with the families at kindergarten events and at the local playgrounds. We chatted together about food and cooking, the best areas to live in, which schools we were hoping our kids would go to. Normal stuff, basically. In German. Some people told me how their families had moved areas to make sure that the kids got a better education, didn't hang out with the wrong crowd, and so on.
A lot of the kids started out at kindergarten at 2 years old and speaking only Turkish. Watching them through four years of kindergarten, you could see how many families were actually suppressing use of Turkish in an attempt to foster the German language skills of the children. Not all, of course, but many.
Turkish women, whether with or without headscarves, work in the area in pharmacies and doctor's offices as well as in restaurants and clothing shops. There are Turkish women working in local supermarkets including German chains as well as Turkish groceries. And they are not just working at the cash register either, but stocking shelves and working at the butcher's counter.
Of the Turkish women I know personally, there is a kindergarten teacher, a secretary, a driving instructor, a social worker, and a lady who volunteers at the local Red Cross office. Some wear headscarfs and some don't. Some of them, if you didn't know them well, you wouldn't know they were Turkish.
On the headscarf issue in Germany. There's a lot of issues going on there, and it can't just be boiled down to refusal to integrate or belief in having to cover up.
To give just a single example of how it fits into wider issues, it's worth remembering that wearing a headscarf is prohibited in many circumstances in Turkey. The 'freedom of the West' can be taken as the freedom to wear a headscarf if you want to as compared to not having that freedom in Turkey.
Anyway, its all rather a tangent to the actual topic, so I'll stop here.
