@uofcparent according to a link in the Slate article, it appears that 34 other notable institutions are jumping on the “Suck Up” bandwagon. Notably, Princeton, Columbia, JHU, Georgetown, Clarmont-McKenna, SUNY-Buffalo, Chapman, MSU, Mizzou System (guess the other way didn’t work so well for them 
) Citadel and others have all officially adopted the University Chicago statement (or a close facsimile). A whole lot more are in process. Guess all those nebulous College Republicans, Right-Wing donors and parents have a fairly large pull

Part of the confusion among so many of the students is that they equate stuff like “We don’t support trigger warnings or intellectual safe spaces” with “now you are forbidden from handing those out”. That is NOT what the University Statement says, since “forbidding” would be as restrictive to speech as “mandating”. UChicago was not in the habit of micro-meddling in the academic conversation that takes place and made that clear in its statement. It did so because other universities WERE starting to micro-meddle and getting push back from their own faculty. As usual, UChicago started a trend by being what it is. When you stay the course while the winds of sentiment blow strong in one direction, and then the other, you are naturally going to look very different - even radical - in both instances.
