Quite interesting.
First line of defence: it's not that important an issue.
I pointed out it was, and that for every woman (me!) prepared to have a barney with him, there would be ten more who just wouldn't vote form him.
Second line of defence: oh well I don't really bother with conference, didn't go it's not really relevant.
Well, you have just found that it is relevant as it matters and it is losing you votes. perhaps you should go and put the other point of view then.
Third line of defence:
I was thinking of standing as an independent but it's a bit late for that now.
I took that as a win...
He also tried to tell me that the suffragettes would be very disappointed in me if I did not vote for someone. Which has at least made me think that I will go and spoil my ballot.
