Ignoring the obvious attempt to bring fascism as somehow not right-wing, which is all too common on the right today, FB/Twitter etc. make exceptions for governments/public figures, including Donald Trump and the DoD.

I don't think they should, but I also know that if they didn't, Trump and others would get banned and the cries from the fake free speech worriers, (who are quiet as heck on ie BDS), would be a lot louder.
