To be fair to HN, I mean, your comment kind of indicates your own political sensitivity as well right?
I, personally, don't mind political content. I find it interesting. That said, I'm not going to get on fellow HN'ers when they downvote or flag it. That, in and of itself, would be a political act rooted in sensitivities.
If you have reasons, in particular, that posts or comments should not be flagged, I'd personally encourage you to outline them. Then let the chips fall where they may. Getting emotional only decreases the overall quality of the conversation. And, presumably, outlining your own ideas would get whatever viewpoint it is that you wish to push, into the thread.
