Republicans must have developed arthritis by all the extended unnatural positions they’ve put themselves in to appease Democrats, and yet there’s a meme bubbling up in the media that the GOP is full of ruthless operators, while the opposing party is perversely enjoying its own humiliation.

This, like other things you read in newspapers or watch on cable news, is the exact opposite of reality, but MSNBC’s Joe Scarborough fed this garbage to his audience on Friday.

“As a former Republican, when we lose, we get really angry and we knock people’s heads off their shoulders,” he said. “It’s just a natural instinct. … Who’s the Democrat that’s a strong, tough liberal or the strong, tough moderate or the strong, tough conservative Democrat who’s going to lead this fight?”

Donnie Deutsch, a frequent “Morning Joe” guest without obvious purpose, wondered where the “fresh, aggressive, rageful voice” is in the Democratic Party.

Politico editor-in-chief John Harris wrote in a piece earlier this month that there’s a “fear” among Democrats “that their party loses big power struggles because Republicans are simply tougher, meaner, more cynical and more ruthless than they are.”

Liberal filmmaker Michael Moore said last month, “It’s amazing how we talk as liberals. We always want to be nice and maybe be fair.”

You know those Democrats: the Quakers of politics.

Wait, that’s not right. What I meant was: the party that, with a crucial assist from the media, nearly derailed a Supreme Court nominee by accusing him of attempted rape and, worse, getting drunk in college.

What I meant was: the chosen party of Rep. Maxine Waters, D-Calif., who successfully called on the public tormenting of Republicans, like Secretary of Homeland Security Kirstjen Nielsen, who in June was chased out of a restaurant by a liberal mob, or Texas Sen. Ted Cruz, who enjoyed the same fate in September.

Republicans like Iowa Sen. Chuck Grassley nearly drive themselves insane accommodating Democrats, as when he delayed a vote to advance Brett Kavanaugh’s nomination not once, not twice, but three times.

Then, of course, there’s Sen. Jeff Flake, R-Ariz., who delayed the full Senate vote on Kavanaugh for another week, a needless cave to Democrats (and the media) who insisted Kavanaugh undergo more vetting from the FBI.

You’ll recall that Democrats then complained that the investigation wasn’t real and Flake’s status as a media hero came to an abrupt end.

The Kavanaugh episode showed that Democrats and the media have seized the #MeToo movement for political purposes and yet no elected Republican has aggressively confronted this.

This week on ABC’s “The View,” Joy Behar said of Kavanaugh’s accuser, Christine Blasey Ford: “She said it was him; you know who it is who’s assaulting you, and if that’s all true, we’re stuck with this guy for the rest of his life. He’s very young for the Supreme Court. It’s a huge problem for this country.”

Had a “tougher, meaner, more cynical” Republican been the guest that day, he or she would have exposed Behar for turning unsubstantiated sexual assault allegations into a political tool.

But the guest was Sen. Ben Sasse, R-Neb., who would only compliment the #MeToo movement as “really important.”

Even President Trump has shown a tendency to collapse under the ballistic pressure wave Democrats and the media can create when their hearts are in it.

During the summer, the administration did nothing more than enforce existing law — a novel concept, for sure — when authorities moved apprehended illegal immigrants at the border and put them in prison.

Minors aren’t allowed to accompany their parents to the lockup so they were instead placed in detention centers to wait.

But Democrats and the media pushed the idea that this was a “new policy” and that Trump was “separating families,” even though the Obama administration had done the same thing.

After a few weeks, Trump (one of those “ruthless” Republicans that John Harris wrote about) relented and signed an executive order that stopped the full law enforcement.

In the lead up to the midterms, Democrats have attempted to thwart a Supreme Court nomination, succeeded in getting Trump to back down on a major immigration fight, and inflamed mob protests.

The media aren’t really interested in that, but where are all the vicious Republicans we keep hearing about?
