No, what it proves is that users will flag unsubstantive flamewar posts on Hacker News, regardless of the topic or the commenter's position on the topic.

This is a good thing. Posts like your comment here break the site guidelines badly*, and the users who flagged it were quite correct to do so, regardless of your (or their) political opinion.

* for example, this one: "Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.", and this one: "Don't be snarky.". Can you please review https://news.ycombinator.com/newsguidelines.html and stop doing those things? We'd appreciate it.
