The actor, who was hired as a writer in 1988 before becoming a cast member in 1990, declared it pained him to denounce his alma mater.
Yet he states he can pinpoint the specific moment when the show abandoned laughs to make political points.
He announced it was when McKinnon as Hillary Clinton sat down at the piano and mournfully sung Leonard Cohen's Hallelujah after her momentous election defeat.
McKinnon wore one of Clinton's trademark white pantsuits as she played the late-Cohen's iconic song on piano in-front of the studio audience.

The Emmy-winner appeared to become visibly emotional throughout some of the more poignant moments in the song.
"I hate to crap on my old show," Schneider explained to The Blaze's Glenn Beck. 'I literally prayed, 'Please have a joke at the end," Schneider announced he recalled.

"Don't do this. Please don't go down there. And there was no joke at the end, and I went, 'It's over. It's over. It's not gonna come back.'"
Schneider explained: "When Hillary Clinton lost — which is understandable why she lost. She's not exactly the most logical person in the room. And then when Kate McKinnon went out there on Saturday Night Live in the cold opening and all that, and she's dressed as Hillary Clinton, and she started playing 'Hallelujah.' I literally prayed, 'please have a joke at the end. Don't do this. Please don't go down there.' And there was no joke at the end, and I went, 'It's over. It's over. It's not gonna come back.'"
TRUMP READY TO DEBATE BIDEN 'ANYWHERE, ANYTIME, ANYPLACE,' BUT WILL IT HAPPEN?
Schneider states the show has now essentially moved on from comedy into politics and is now 'indoctrinating' people.
He further thinks that SNL is not the only culprit and is equally critical of late-night comedy shows in general, claiming there's not an "independent voice" among hosts including Stephen Colbert and Jimmy Kimmel.

"You can take the comedic indoctrination process happening with each of the late-night hosts, and you can exchange them with each other. That's how you know it's not interesting any more. There's not an independent voice any more," the Deuce Bigelow star announced. "It's all indoctrination by comedic imposition."

Schneider, who is well known for his conservative political views was further unhappy with Alec Baldwin's impression of Donald Trump.
"I don't find his impression to be comical because, like I said, I know the way his politics lean, and it spoils any surprise. There's no possible surprise. He so clearly hates the man he's playing," he announced in 2018.
