It shouldn't need to be said that if you want people to take your stated political convictions seriously, as in I may or may not agree with everything you say, but it sounds like you've thought your positions through and are making an effort to be intellectually honest and consistent, then you don't pull cheap stunts like that. Spicer is not allowed to be in on the joke, because he is the joke; worse yet, he was the willing homunculus for a lying, corrupt, demented old man and his crime family.
In making Spicey the Sammy the Bull of the west coast political smart set, Stephen Colbert and whoever else masterminded this nonsense exposed themselves once again that, like their media weasel counterparts, clickbait and eyeballs rank over everything, including political principles. This little asshole actively worked to undermine this nation's confidence in their institutions. He willingly enabled the most corrosive political figure in our lifetimes to seek rhetorical cover behind lies and transparent bullshit. No one forced him, and I'm sure the checks cleared.
Spicer is a henchman, a dogsbody. He should not be stunt-cast on the Emmys, or invited to Harvard as a guest lecturer, He should be completely bereft of further career options, and go back to his rightful place in the food chain -- as the White House Easter Bunny.
