In his hate speech he says
"Every single Muslim who disapproves of my actions is a sleeper cell, waiting for a signal. I am warning you Oh America!"
And here's the thing. In the light of these rantings, who sounds more rational? Trump who claims he'll deport every single one he can and block every single other one from entering?
Or those who say he's a paranoid racists???
People like this get away with this kind of ranting because they believe that we, the west, are fundamentally weak and unwilling to take measures which might be deemed racist by a minority of the population.
I'm reminded of a statement by one analyst shortly after Trump won.
"Well at least the press won't have a problem working out what Trump wants to do". All they have to do is listen and repeat it.
We shall see.
