Ask HN: Your most controversial comment?

I'm all for intelligent comments that deserve nothing but praise. But from an anthropological perspective, I think the comments that receive both up and down votes are interesting - and something that only visibly manifests in people's replies.

I've noticed a couple times when I comment that my karma will oscillate quite a bit, and I'm wondering if anyone here recalls (and can link to) one of their own comments that really split the community?
