"Vitriol" vs. "Invective"

I find it ironic that in one paragraph, Gil appears to condemn this "one guy in particular" for calling Democrat's rhetoric "hateful venom" and "vitriol".

Yet he turns around and calls the Republican response "invective".

invective: abusive or venomous language used to express blame or censure or bitter deep-seated ill will

vs.

vitriol: abusive or venomous language used to express blame or censure or bitter deep-seated ill will

Then he says that's done by those "whose entire modus operandi involves accusing others of the very shenanigans they immerse themselves in, day after day."

Tried looking in the mirror lately?
