You're not missing anything. In one video a little piece of spit flew out of his mouth for like 2 frames, and in another he had a little glob of spit for like 5 frames, and then they played it slow motion and zoomed way in and repeated it a bunch of times because otherwise it would have been comically underwhelming.
The raping, grifting, misogyny, racism, tax evasion, lying, top-secret document mishandling, pandemic mishandling, veteran-hating, handicapped-hating, immigrant-hating, insurrection starting are one thing... but foamy saliva is where I draw the line.
Yeah. He killed like a million people by bungling the covid response, and conspired with one of America's shooting-war enemies (at least one) to get a whole bunch of CIA assets killed in the field. Like dozens of them. A foreign government hacked up an American journalist with bonesaws and took him out in pieces, and Trump came out and said, well they gave me a bunch of money so who cares about one journalist.
And all that is just the stuff that we know. He's like a supernova of treasonous and criminal behavior. No matter how bad you might estimate it is what he did, it's many many times worse.
