I think the important difference is that Obama didn't threaten a slaughter by the military then…

First Obama didn't incite more fuel into the violence by send in military to shoot american people and tweet "when the looting stars shooting starts"

Second it's a domino of all things happen with a bad leadership:
The pandemic he still not taking responsibility that kills more than 100 thousand people and infect over 1.500.000 people
Depressions with millions unemployed
Him try to falsify information of vote by mail
His rage over Twitter fact checking him
and now this
and that's just in 6 months of 2020 people.
