Taking this as a serious question, it wouldn't be hard to make a list of topics that get instant flagging on HN. I suppose the reason why people don't bother is they expect any attempt to explain would also be downvoted to oblivion.

I'm not sure it's that cut and dry. But I agree there are some viewpoints more likely to be downvoted than others.

I strongly disagree with Graham's view that disagreement is a good reason for downvoting.
