Dissing: Disrespecting, insulting.
To be honest, I’m glad he’s not going. He’s not worthy to be attending Justice Scalia’s funeral, who was a man of high moral fiber. This POTUS is so arrogant, narcissistic, and disrespectful that his presence would be fake anyway. I can see him now, putting on his liar face and pretending like he cares. No thanks. Good riddance, go play golf!
