What race does a racist have to be?

The British National Party is apparently in uproar over the selection of a supposedly 'ethnic' candidate. Leader Nick Griffin would like the party to become more racially inclusive, providing equal opportunities to become a fascist scumbag. (provided you're not too 'ethnic', of course - members are reassured that the candidate in question is 'not a Pakistani Muslim.) Sharif Gawad, a 'totally assimilated Armenian Christian' whose mum is a fan of Omar Sharif, has jumped at the chance to seize such an opportunity. The BNP rank and file, meanwhile, are less than enthusiastic, questioning the point of joining a racist organisation if one then has to be racially tolerant .
I'm stuck deciding which element of the above story is the most mind-boggling.
