There is antifa and there is antifa.
One is anti fascist and the other is anti facts.
On Inauguration day Trump blamed antifa for one broken window and dozens were charged for rioting. We all know about Trump's anti facts and alternative truth.

In this time of cold truth war we are all vulnerable believing almost anything. All I have is 'what is more likely possible' and that too is untrustworthy.    So I choose to believe both boogymen exist.

It would be possible for Trump to anonymously make himself president of antifa and and stir the pot (a trick he did before in 'call in' shows back in NYC.)   In short nothing is as it seems but crime is going big time.
