And now the HN mods have flagged this comment as off-topic, which causes it to be collapsed by default for all viewers of this thread. Everyone needs to specifically click the [+X] on it to even be able to read it.

Regardless of that, it seems like you're upset because of some mistaken expectations of what HN is for. It's not trying to be a "general purpose" site where you should expect to be able to discuss any and all topics. It has a pretty narrow focus, and users tend to aggressively flag posts about anything without a clear connection to the set of subjects that they feel "belong" here.

You shouldn't try to treat HN as a place where you'll be able to find general news about the world or discuss anything in particular, no matter how important you feel it is. It's a good site for its particular niche, but you're going to end up with a myopic view if you aren't also using other sites too.
