I don't especially think those who recklessly promote denial of the Holocaust should have any rights at all.

In that case we are doomed to differ. I fundamentally believe that human rights have to extend to all humans, no matter how odious. Part of that stems from the selfish belief that if they don't, people who find my way of life abhorrent can take those rights from me.

I also think the best way to deal with whackjobs is to have their beliefs out in the open for all to ridicule and beware of, but that's a separate issue.
