The Q is deep state theory IS childish. He wasn't calling the holder of that opinion childish, per se.
I call that opinion childish as well. Opinions based on wishful thinking are childish. Adults look at evidence, reason, and logic to form opinions. To think that the "deep state" would expose and attack itself defies logic.
If one holds childish opinions are they childish? That is not the point, but perhaps they are.
I will call an opinion childish if I think it is, and I approve Jeremiah's use of the term for that childish opinion. We cannot be afraid to tell the truth in this, the age of Trump. Political Correctness is cancer.
Coulda' been worse. Coulda' said retarded. So there is that. Eh?
