Lastest update of the FAQ (updated 12 Mar 2007) on the BNP.org web site answers your question in typical simple terms:
"vi. Why don't you let blacks and Asians into the BNP?
For the same reason the Girl Guides don't allow boys to join. Does that mean they are sexist? Does it mean they hate boys? Of course not, it's just that their aim is to cater for the interests of girls, and similarly the BNP isn't racist, but our purpose is to cater for the interests of the indigenous British population. The indigenous population of Britain is now the only group which is facing systematic, legalised and institutionalised discrimination, harassment and oppression. That's precisely why the British people need the BNP - because we are the one and only organisation that has their interests at heart. There are hundreds of organisations exclusively for blacks or Asians, but only one organisation for the indigenous population - the BNP. "
