Could be LGBT activists protesting the president’s directive on TransTroops. Could be Muzzies. Could be Lefties protesting the President’s plans for the military taking lead on The Wall. Could be a combination - never assume these vermin don’t want to work together when it suits them, even if they would normally despise each other in different situations.
My money would still be on a ISIS type individuals or groups. However, they are pretty stretched out and show a degree of incompetence. It is, in fact, weird and might even be Antifa pumped up by the anti gun demonstrations (if that even makes sense).
Why, it could be mozlum queers.
