The same issue is with any anti-something community and also on reddit. Eventually they turn into picture-of-text karma farms.
It's really easy to unite people in negativity when being against something in common, but it's a lot harder to unite them in being for any solution.
I dislike the idea of copying subreddits to here for that reason. The problems follow along too.
It might have been more useful on Reddit, because of the massive userbase, to shout out anti messages from the roof tops, hoping to sway some opinions, but without any suggestions for solutions it's just rabble-rabble.
Imagine if the president said "look anti-car people, we hear you, what do you want?"
And it would still be "rabble rabble", because the anti-car communies consist of people who want to: ban large SUVs and trucks, have more public transport, ride their bicycles, have more pedestrian streets, change the property zoning, change politics, etc.etc. and they don't necessarily agree on what they want.
