I can feel how badly you're about to get shit on by some people on this site. However, I'm gonna try to be a little less reactive and offer a simple reason why you aren't accurate in what you're saying.

in practice if enough narrow-minded pigs accumulate to grunt their message in harmony – what do they care what anyone else thinks?

That's one of the issues that became apparent to me when I first joined, and I saw it sort of as a formation of circles-- When we block out a range of things we dislike and the 'main' group more or less just follows each other, we completely isolate ourselves from anything else that might happen on Hubski. Hubski is a universe, and you're a planet that can swing through with some other planet homies and create a galaxy.

There's a really, really, really small chance that your galaxy will ever collide with anything else happening on Hubski because you mute everything new inbound that you dislike. So will your homies. What we're lucky to have on Hubski is one huge galaxy filled with all the 'power-users' and great content sharers and creators, and everyone else who views them. There aren't enough active users that disagree with each other to such a polar proportion where there is a separate community created that blocks out the first. We're not missing anything good that happens on Hubski. You might have black holes and other phenomena (see ahametals) that are some of the most active things on Hubski but comletely ignored and shut out of what we experience. I'm okay with that. it's how it works, there could be a thousand ahametals and they'll all be shut out even if they're the most active grunters on the site.

So when the screaming pigs start grunting together-- what do we care either?
