What Al said in another thread about the nature of the missing of the point being significant and communicating quite a lot deserves, I think, to be reiterated here.
Ftr, if I actually believed that followers of Christ were like you, or dare I say it, even BRTD, I would vote differently but I know him not as a man, but someone whose followers use his name to punish others. If Christ was the first Christian, and one believes that Christianity has had a negative societal impact at the global level, I don't think an HP vote is unreasonable. But I don't have a high opinion of people who aggressively mock and berate people of faith either.
DemPGH I think gave the closest answer to how I feel but "protest vote" and all.
