The BNP received 192,746 votes in the 2005 general election (0.7% of the total cast) and 18,020 in the 2008 London Assembly election (also 0.7% of the total cast), so "millions" have not voted for the BNP. It's a bit difficult to see how you could extrapolate those figures to suggest "millions" this year, especially when turnout is traditionally low for local and European elections.
Even if there were millions, it would still be right to attack a party espousing bigotry and hatred.
