Quote from above

"how common inter marriage was, for that is the only way proper integration can be achieved ......and it must be achieved or society will not survive."

It's very common. in fact society survival statistics by your logic were given a boost when marriage between people of the same sex was thankfully recognised in law.

Integration can only be achieved where equality is promoted. Luckily, here in The UK, that is the case. It may be a shock to you and your blinkers but most people don't put their superstition above their love. It is just as possible to be a boutique Muslim as it is a boutique Christian. Or non practicing, culturally, heritage, labelled by others.

Identifying real people by their arbitrary label went out of fashion in the real world years years ago. It's just the preserve of newspapers, UKIP and terrorists now. It is demonstrated every day in every walk of life that you can keep your ingrained superstition and still get on in life.

It never ceases to amaze me how when people from other cultures are shunned, it is they who are then accused of not integrating.
