Jim:
You said that Britain was: "prepared to see refugees drown rather than let them pollute British soil "
I asked for any quotes you could give to back up your assertion. You have still not provided any. The only reasonable assumption is that your claim is unsubstantiated. I will happily read any links that you can give which show that: Britain is prepared to see refugees drown rather than let them pollute British soil.
In the absence of any such links, I would hope that you would withdraw your claim.
