Obama got in a war in Lybia and performed countless extra-judicial targeted strikes and assassinations and you mostly saw cheers on the left, which is fine. But suddenly, with Trump in office, the same things will now cause World War 3 to start and the draft to be reinstated. One of the reasons I don't sport a red avatar myself. Neither will happen, by the way.
Those actions made me extremely upset, as well. I certainly didn't cheer then, especially Libya.
Though he didn't literally assassinate a high-ranking government official, either.
