The things he is saying and doing are not a joke, and should not be treated as one. The facade of "he's just messing around to make the left angry" is false and thin. He is telling you exactly what he aspires to be. Or, more accurately, he is attempting to assert that he already is one.
If you believe in the ideals that America was founded upon, you should be angry. Fascism is here, and it's up to us to resist it. Please.
