Oh, but didn't you know? That is the OFFICIAL stance of the BNP anyway. The fact that 100% of their members are raving racists who would gladly see a genocide of all non-whites is COMPLETELY irrelevent and coincidental.
Plus almost all of your "suggestions" are unworkable. Send terrorists to a third world country? Yeah, and what third world country is going to agree to take them? You can't just put them on a plane to Dar Es Salaam and not expect 1) them to come straight back again and 2) not to seriously annoy the government you're undermining by forcing ILLEGAL IMMIGRANTS (cause that's what they'd be) into their country.
Ending legal immigration will see the NHS die. Simple as that. How many British dentists do you know? I can't think of a single one. How many British opticians? Not very many at all. So would you like to pay american rates for your healthcare? Because that is what you'd have to do.
I think every government would very gladly empty hostels housing ILLEGAL migrants - illegal migrants do nothing for the economy; it's not that the government don't WANT to get rid of them, it's often that they CAN'T get rid of them - or of course you are assuming everyone with a Polish accent is illegal.
And of course, if the BNP DO get into power you will be on the boat back to India. They will not care you are British, probably born in Britain maybe even to people themselves born in Britain, and they will not care that you support them. You will be straight back to India, or you will be killed.
And incidently you are not allowed to become a member of the BNP because you're not white, I saw that on their own website. That just goes to prove this party cares about very little other than race.
