People sling accusations about propaganda based entirely on what they already believe. Anything they believe counts as truth, while anything the other side believes or supports is propaganda. This is how the human mind works under pressure. Everyone does it, and it's more evident than ever these days. Unfortunately, it's no basis for moderating an internet forum—or at least not this one.

You need to follow the site guidelines the same as any other user here, and if you keep breaking them we will ban you. You can post thoughtfully and substantively even when you disagree with something so strongly as to regard it as propaganda.

As for "you did nothing to stop that" - if you see a post that ought to have been moderated but hasn't been, the likeliest explanation is that we didn't see it. We don't come close to seeing everything that gets posted here. People can let us know about posts that are breaking the site guidelines by flagging them, or in egregious cases by emailing hn@ycombinator.com. However, someone having a different view, even on a passionately divisive topic, does not automatically mean that they're breaking the site guidelines.
