Speaking in a purely personal capacity, I should like to put on record my good wishes to each and every nationalist party, even the “inappropriate” ones, whose leadership contains Holocaust deniers (and/or former Holocaust deniers), for example.
Such deluded individuals are more to be pitied than scorned. “Father, forgive them; for they know not what they do” (Luke 23:34). They are entitled to exercise their right of free speech, regardless of the damage they do (or have done) to the nationalist cause. At least, they are so entitled under English, Scottish and Northern Irish law. The law of some of our so-called European partners is a horse of a different colour.
Not that the general public pays much attention to people who deny the Holocaust. They tend to be more focused upon their own present and future than upon the rapidly receding past. Nevertheless, there surely can be few who, upon mature reflection, would feel confident in electing someone whose finger might one day hover over the nuclear red button, if they knew that individual had once publicly denied the Holocaust.
The crucial question is: can one trust the judgement of such a person in other, more important, matters?
