Edit: rather oddly I just posted an innocuous comment (a couple of Wikipedia links) and it was immediately dead on arrival. What's going on there? Wild auto-modding.
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.
