OK it's fair enough to call for a debate and discussion on immigration.
However don't back the BNP because of that issue alone.
If I'm cold at night setting fire to my house will address the issue, but it will make a mighty fine mess of everything in the process.
The BNP are so stupid/ignorant/nasty that how can you trust them to deal with the problem?
These are people who deny the historical facts of the holocaust.
These are people who disagree with mixed race children (well that's every Anglo-Saxon child in trouble then).
These are people who managed to use foreign models in a poster calling for British jobs for British workers.
These are people who didn't see the problem is using a Polish flown Spitfire to advertise for them when they want to kick the Poles out.
How can anyone trust them with anything? I'd feel wary trusting them to tie their own shoe laces.
