But he either is not aware or doesn’t care the historical context of the phrase he used especially coming from the mouths of people in position of power
I think he's not aware of it, and that's important. Because if he was aware of it, then he'd know it is often used as a threat, and a prelude to the deprivation of civil liberties. But if he
doesn't know that, then it isn't fair to assume that's what he intends.
He's simply calling the press out for a clear bias intended to steer elections and political debate, and to force their vision of their preferred society down our throats. So in that sense, they very much are a political enemy.
