Congresswoman Marjorie Taylor Greene (R-GA) continues making headlines for all the wrong reasons.

Greene was expelled from her committees after resurfaced social media posts revealed she expressed support for the execution of her now-colleagues and for deranged conspiracy theories that former Secretary of State Hillary Clinton murders children and drinks their blood, that the devastating California wildfires were started by space lasers, and that school shootings are coordinated by Democrats to weaken public support for the Second Amendment.

At the time of the expulsion, Greene insisted that she felt freed by the development, because she'd have more time out of committee to spread her message beyond just her constituents.

We're starting to get a better idea of what that looks like—and it's not pretty.

This week, news broke that—as businesses begin to reopen—President Joe Biden's administration was considering an initiative for the private sector creation of a "vaccine passport" that would allow Americans to easily prove to businesses they've been vaccinated against the virus that's killed over 500 thousand Americans.

Greene, who rages against the wearing of masks and rejects virtually every safety measure recommended by health experts, leapt to decry the idea of a vaccine passport on Twitter.

For the unfamiliar, the Christian bible, particularly the book of Revelations, details an insignia or mark for followers of the Antichrist—and a false prophet who manipulates people into receiving the mark which seals them out of Heaven.

The pandemic has already prompted conspiracy theorists to speculate about a "mark of the beast," and it seems to be the latest conspiracy theory Greene is tacitly promoting.

People were astounded.

The White House has emphasized that the vaccine passports would be a private sector initiative to be used as a tool for businesses who choose to request proof of vaccination for their patrons, or—as is already the plan in New York—for venues like Madison Square Garden to begin holding large scale events.

The constant refusal of some Americans like Greene to help build a safe way forward was infuriating to many.

As many pointed out, proof of vaccination is already required for a number of processes in the U.S., including school enrollment, military service, and some international travel.
