I've made this point about Obama fans a number of times. Many truly are oblivious to the condescension, and they assign very ugly motivations to those who aren't. Trump's rhetoric is far more divisive, of course, but that doesn't erase how others conduct themselves.
I definitely think Obama is much more divisive than his admirers think. They are essentially blind and deaf to his condescension and it’s bizarre to me. Even more bizarre, however: MAGA and Trump apologists being outraged by Obama/Clinton’s “divisive” rhetoric without being even slightly troubled by Trump’s far worse and far more sustained rhetoric of demonization and delegitimization never mind “division.” It makes a vast amount of their panty-bunching whining seem almost pretextual (though I don’t think it is. I think a lot of it is the same kind of blindness and deafness.).
