i have no idea why when she has openly stood for a public vote she cannot at least give answers to those of us who have a geniuine interest as to her motives.

Because the beliefs of the BNP are predicated largely on a series of lies, and therefore won't stand up to scrutiny. They might sound OK when shouted out on a street corner or in a pub, but examine them, test them and look for the truth and they just crumble.
I, too, would love to hear George's justification, but I'm guessing that when she thinks deeply about it she has a hard enough time justifying it to herself without coming on here to do it.
