I didn't see the original comment and appreciate your positive intention, but you might have been slightly off in practice there.

By "gratuitous negativity" we're mostly talking about how community members treat each other and their work. It's ok to kick ideas around a bit harder. And certainly a few uses of "fuck" don't hurt. It looks to me like kang was just being enthusiastic.

That kind of thing can break the guidelines if someone overdoes it repeatedly and their comments add no new information or arguments. But that's not the case here.
