There isn't a rule. The comment you're replying to just shares the author's preferences. If you like their way of thinking, then maybe you'll think about that when you're about to hit the submit button on something not related to tech or hacking. If you don't like their way of thinking, then maybe you'll submit the top post from r/politics every morning. It's up to you.

I will say that I haven't enjoyed the political discussions on HN. They get too heated, too quickly. But, I simply don't participate much in those. I'm not upset if other people enjoy them.
