(RNS) — Imagine a meeting of the combined editorial teams of Mad Magazine, Cracked magazine, and the late, lamented National Lampoon. Their assignment: Come up with the wackiest conspiracy theory anyone could ever imagine.

This is what they might have invented: A secret cabal of Satan-worshipping, cannibalistic pedophiles is running a global sex-trafficking ring. They had been plotting against then-President Trump. Among the cabal: Hillary Clinton, Barack Obama and George Soros.

That conspiracy theory is called QAnon. It functions as a cult. Thirty percent of Republicans have a favorable view of QAnon.

Which means there is a strong possibility you know someone who believes in QAnon.

Or, the editorial teams might have come up with another wild theory — that a secret space laser, operated by the Rothschilds, is responsible for wildfires in California.

That is what Rep. Marjorie Taylor Greene (R-Ga.) believes. She also believes in QAnon.

Want to know what else she believes?

• Muslims don’t belong in government.
• 9/11 was an “inside job.”
• The shootings at Marjorie Stoneman Douglas High School in Parkland, Fla., Sandy Hook and Las Vegas were all fake.
• “Zionist supremacists” are masterminding Muslim immigration to Europe in order to outbreed white people.
• Democratic office holders should be executed.

Marjorie Taylor Greene must be removed from Congress.

Now.

Either her constituents in northwest Georgia must demand she resign, or her Republican colleagues must demand she resign.

First, her beliefs are unhinged.

They are so far beyond the range of acceptable opinion in this country as to be, frankly, insane. While I am not a mental health professional, it is hard for me to imagine a sane person believing this kind of madness. No doubt she is not alone; her constituents must include those who agree with her, and I am sure the fever has spread way beyond the boundaries of her congressional district.

But, let me be clear: This is a communal psychosis — no different from the various libels of the Middle Ages. Last week, I was teaching our high school students about the years that led up to the Holocaust. They saw how a nation found itself under the spell of politically induced insanity, and they understood those tendencies have far from disappeared.

Second, her beliefs and behaviors are cruel. 

Marjorie Greene can believe whatever mishigas she wants.

But, Rep. Greene cannot — especially when her beliefs provoke her to do real damage to people, like harassing Parkland survivor David Hogg. Her fellow Republicans have appointed her to the House Education and Labor Committee. I am, for not the first time this month, without sufficient words.

Third, she is an anti-Semite.

It is bad enough she believes in a Zionist conspiracy. She also believes the Rothschilds are behind a conspiracy to ignite fires on earth from space.

Why the Rothschilds? Because they are one of the wealthiest dynasties in the world — and because they are Jewish. “Rothschild” has long been a code word for “international Jewish bankers.” It is not even a dog whistle. It is blatant, out-loud Jew-hatred. Nowadays, George Soros has replaced the Rothschilds in anti-Semitic ideation, perhaps because his name is both easier to spell and a palindrome.

Fourth, her actions threaten the future of the Republican Party.

After the insurrection of Jan. 6, many Republicans engaged in a kind of hand-wringing, protesting (feebly, in some cases) that those thugs did not represent Republican beliefs. Some have sought to distance themselves from Trump, saying he does not represent the Republican Party.

Really?

Well, prove it, then.

Because from where I am sitting, the only difference between Greene and the rioters at the Capitol is that she does not wear a horned helmet (as far as we know).

They erected a gallows. And, we already know she wants to execute Democrats.

Republicans must now make a choice.

They can do nothing about Marjorie Taylor Greene. But, they must understand the consequences of their inaction. The Talmud makes it clear: “Silence implies consent.” The nation will interpret Republican silence and/or inaction as nothing less than agreement with Greene’s bigoted ideas.

Now, they can do that — which is to say, they can do nothing. But, please, do not be surprised when citizens conclude the Republican Party is now, inextricably, the party of Trump — and that it really is the party of Jan. 6.

Let them not be surprised when Jews get the message. The Republican Jewish Coalition has condemned Rep. Greene, as have other major Jewish organizations. Now it is time for Jews in the Republican trenches to get up and scream about her.

Because your failure to do so will signal to other Jews you just don’t care that much about the Jewish thing after all. Your failure to do so will signal to other Jews the Republican Party means more to you than Jewish integrity — that you are willing to undergo self-erasure for the sake of a party you never dreamed you would be part of.

Or, the Republicans can stand up, along with Greene’s constituents, and they can say: No, this is not who we are.

Residents of northwest Georgia, you are better than this. You do not deserve this woman to represent you in Congress, and she does not deserve to represent you.

Republicans, you are better than this. Your party needs serious introspection and serious repair. She is not helping. She is hindering the task. More than this: She is not the face Republicans should be showing to the United States, and she is not the face the United States should be showing to the world.

Marjorie Greene is unrepentant. Told that her views are offensive, this was her response: “I will never back down.”

We should not back down, either. Not until she is gone from the halls of Congress.

I urge you: If you have a Republican congressperson, contact that lawmaker’s office and demand action.

America is watching.
