It has been proved through history that people of different religions, races, colours, ethnic backgrounds etc dont always get on.
Wars have been fought all through history for these reasons recently in places such as Africa, Ireland, Cyprus, India, Yugoslavia, and the US and UK, France and Germany have had recent riots caused by ethnic tensions.
But our totally stupid politicians have decided for the last 20 or so years to bring in millions of people from all over the world with different backgrounds, and they just expected us all to live together without any problems.
There was BOUND to be problems, and I think they are getting worse.
In 50 or 100 years time we will look back as this mass immigration and realsie what an awful mistake it was.
btw I am NOT against some immigration. A small amount of immigration is good for a country.
But when you get whole communities (or even whole cities) taken over by "immigrants" then things have gone to far.
It is a bit like putting sugar in your tea. One spoonful is OK, maybe two spoonfuls is ok, but when you pour in half the pack of sugar into your tea cup then things have gone wrong and it will taste awful.
