This has been on the cards for a while and to be honest the Pakistani/Bangladeshi community need to change and start integrating. ... So to the point of the OP, its a very good thing that workers from Asia are being stopped, they can do what all other normal businesses do - train and recruit the best person for the job, not restrict it to male Muslims.
VP, the very fact that you have several very good Bangladeshi friends is a clear indication that your remarks have no racist intent, but I think you misunderstand the nature of society. Have you, for example, ever visited Happy Valley in Hong Kong ? All the (rich) expatriate Britons live there in one giant enclave, and integration with the local population is almost non-existent. In Abu Dhabi, where my wife works, all the expatriates (from wherever) club together, speak English to each other, and never have any interactions with the local Arab population other than through commerce. And when I went to France with a group of Rotarians, as soon as we were back in the hotel we all reverted to speaking to each other in English. It is simply human nature to want to socialise with other members of the ethnic group within which one grew up -- I count myself very fortunate in having real friends in many countries around the world, and being married into a Chinese/Vietnamese family I take part in many of their activities, but on a day-to-day basis I still spend almost all of my time in the company of my fellow Britons.
