Ok, I've separated your rant from your fears. Here are the fears that you expressed.
"Yes, lets get bent over, work harder to pay ever inflating taxes to support an ever growing population of immigrants. It doesn't matter that my future children will be in a class room of over 50 pupils (wonderful education that'll be) or the ever increasing waiting lists to visit a GP etc etc"
So lets look at them, paying more taxes to support a growing population. Well if its growing then like any business there will be more income. Think of it as Tesco vs Mr Patels corner shop. (I know, but Mr Jones sold it to him) Tesco has more customers, therefore for a number of reasons, that comes from that, they are able to charge each customer less per item, even though their overheads, are much higher than poor old Mr Patel. Same with government income. More workers, therefore more revenue. In
theory less taxes. If not then you ask your limp politian, why they haven't reduced them.
The future of you kids and their large classrooms. More taxes again allows more schools to be built. Higher population, means that there will be more available teachers. More diverse culture means your child will have a better understanding and appreciation of others. Which as we can see would be a major asset to their current gene pool.
GP's, well when you next go to the surgery, take a moment to look around. The chances are at least one of the doctors are from Asia or Africa. The direct result of the multiculturalism that you fear, is there waiting to help you.
While we're on about self interest, of immigration. More people equals more homes, equals more windows, equals more business, equals more money, equals you can afford to IMMIGRATE if you don't like it. WIN, WIN, WIN.
You wont read any of that in the Daily Mail or police statistics. Take the prejudice, from your fears then examine your fears. However if racism, is your only motivation, then non of the above will matters.
