The difference is Jan 6th was an open, immediate, clear-and-present-danger, en masse, armed assault on the Capitol by thousands -i.e. a reasonable, justifiable basis for a deployment of the NG.
Conversely, calling out the NG because one, single, solitary guy who calls himself "Big Balls" got his ass kicked by some teenagers is nothing but an obvious, flimsy af, convenient excuse for weak Li'l Don-Don to play Generalissimo with his army men.
See the difference?
