Anglo Saxons invaded and killed a lot of the local populations
Huguenots were what, 50,000 estimated total across the British Isles?
Indians & Pakistanis were already British citizens from the commonwealth
I appreciate the point you are trying to make but I don't agree with the examples.
The Polish reference is current, not something in the past you make it out to be. Have a look at some of the Lincolnshire communities that were based around agriculture after receiving 300% increase in immigration since the EU expanded. But hey, apparently its fine so long as you dont live there?
