The subject is very polarizing, and posts which explicitly name political parties tend to rile things up. I suggest talking about politically polarizing matters in terms of interests. For example, "Voter ID laws as implemented in the USA tend to result in diminished participation by poor people because [explanation]. Such laws tend to be favored by those who benefit from poor people voting less, and opposed by those who benefit from poor people voting more." This depersonalizes the conflict a bit, and allows us to have the kind of insightful debates that HN is for.
