Calling it now: within the next four years or during a Vance administration there will be a widely publicized shooting/terror attack/assassination attempt committed by a Redditor who openly discussed their motives and plans on the site.
It won't cause an 8chan-tier culling (Reddit is too useful for propaganda purposes for that to happen), but a lot of what plays out on r/politics and the like will be upended. The culture of the site won't transform as dramatically as Xitter did, but a new lineup of powermods and admins aren't gonna be nearly as tolerant of the veiled threats of violence that have gone into overdrive since the election or left wing extremism in general. Not because the new bosses are suddenly /ourguys/ or anything, but the tech lords understand that a distinct realignment is occurring, and a lot of the deranged losers we've been mocking for nearly 2k pages are suddenly gonna be without a home.
Praise be, lads.
(They'll still swear that it's all the fault of Kiwis somehow.)
