What HN specifically requests is "Please don't use Hacker News for political or ideological battle. It tramples curiosity."
There's a difference.
There's several posts already excusing the blog post because it aligns politically with the poster's own views (in this case, that all Jews have collective guilt for Israel's policy.)

The DMCA is political, and is the basis in which most orgs allow public comment. Copyright is political. Patents are political. Cryptocurrency is explicitly political WRT being against governments. Most startups are political, in the way many break laws that the incumbents have to follow.
The people who "dont want to involve with politics" are primarily the ones whose needs are met, and don't care about others' needs. I would claim it's for selfish reasons.
