Our community is being artificially seeded with subversive infiltrators whose sole purpose is to manufacture infighting
Like Greene, Gosar, etc? And the government infiltration of the extremist "freedom caucus"?
As for the Nature article, it's the author's opinion, but also, it's more about community management than infiltration. Based on facts like that extremists also tend to easily be divided. It's also to address hate speech, so why is that a concern to you?
