I am very interested to learn about this issue and would like to offer my full support to the OP for starting it.

It is perfectly possible to discuss this issue without referring to the BNP.

In fact, this issue is most usefully discussed without referring to the BNP.

I'm curious to see the "issues" defined, and to learn the facts.

Leaving the BNP out of it is not only possible but essential as they only see one issue - immigrants are bad and they should be deported.

I suppose it does no harm to look at that question, but I suspect it might take over the conversation and that any other issues might as a result get overlooked.

Good luck!
