Once you’re president, you’re absorbed into the machinery of state, and that machinery expects you to show up. If he wanted to make a statement—and respect all of us—he would not go and let us all know why.

The current US administration shits on the machinery, so Obama doesn't have to play by the rules, too.

Respect should be given only when it is earned.

I give respect until it's shown to be misplaced.

Except in this case, it's been shown to be misplaced. But Obama and Biden will both attend because they're both good men. The question is, will his widow attend?

Right here. I'm with you Bill. My default is respect bc that's how I choose to operate. But disrespect me and now it's my turn.

Respect for the office, though?

There’s no greater disrespect that’s ever been shown to the office than by reelecting Donald Trump: rapist, felon, child trafficker, serial fraudster, and overall pointless bloviating moron

On the other hand, he made fun of Trump more than once, even before 2016, so we know his respect is rather low. So it would be fake respect to attend his funeral.
