I do like talking about politics, especially when it's polite and level-headed discussion (which seems to be the norm here in NH), and a lot of my comments are on that subject. So yes, it would be somewhat sad to see that go.
But the bulk of HN's value lies mostly elsewhere, and not being able to talk about politics here would still keep it a valuable platform and an interesting community to participate in.
So it's really not a big deal one way or the other.
