Not sure if discussion is occurring in any of the individual airline and destination fora now, but it looks like protests are occurring in many hub airports this afternoon. What started at JFK this afternoon is spreading to many cities, including PDX and IAD. A protest at BOS is supposed to be starting imminently according to a local activist thread.
Hope the LEOs working the airports tonight show restraint in what I think is unprecedented for US airports and ports of entry - the only parallel I can think of is the swarming of Ataturk during the coup in Turkey last summer...
