Jon Stewart is standing by his roasting of Joe Biden in the opening monologue for his ‘Daily Show’ return last week … while also mocking everyone who clutched their pearls.

In his second show back for the Comedy Central series Monday night, JS managed to find humor in even the most savage of online messages … noting that those on X get worked up on anything at the drop of a dime — even telling labradoodles to “go f*** themselves.” So yeah, he’s not exactly gonna be crying over the criticism.

Ex-MSNBC star Keith Olbermann and Mary L. Trump particularly took offense to Stewart’s roasting of Biden and Donald Trump — the latter even going as far as to label him “a potential disaster for democracy” as seen in the tweets displayed on the screen.

But JS fired back at the absurdity of the outrage surrounding his monologue … “It was one f***ing show! It was just one f***ing show! It was 20 minutes. I did 20 minutes in one f***ing show! But I guess, as the famous saying goes: ‘Democracy dies in discussion.'”

He sarcastically concluded … “It was never my intention to say out loud what I saw with my eyes and then brain. I can do better!”

You’ll recall … JS marked his ‘DS’ returnby discussing the upcoming 2024 election — in particular, his biting commentary was aimed at POTUS’ age and mental state.

JB’s opponent wasn’t let off the hook so easily — Trump was also roasted for being unable to remember basic stuff … which is a pretty key trait to have if you’re running the country.

Nonetheless, Stewart’s message advocating for new blood in politics is loud and clear.
