There is absolutely no other way to express your political opinion.
We have to keep shoving politics down HN readers throats for their own good.
It does not look like there will be any underpinning of all values and morals that a majority of us will accept or understand. So that leaves us the question: how should we disagree? I think the current way is fine, perhaps we could all strive to be less enflamed by views contrary to our own held beliefs, but do not think that the situation couldn't be way, way worse.
