I am only wondering how you managed to avoid getting blocked by him up to now.

Facts and figures - Royal Entomological Society Did you know? 1) Over one million species of insects have been discovered and described but it is estimated that there may be as many as 10 million species on earth. 2) There are approximately…

Fun fact: I just learned that there are approximately 1.4 billion insects for every person on earth. www.royensoc.co.uk/understandin...

He doesn’t believe in scientific evidence. Peter Hotez’s book about his daughter w autism (and how it was not the fault of vaccines) came from conversations w rfk jr., who was not moved. Who knows if he is insane, but he is very effective at destroying public science and vaccine access.

Cuts like these reinforce my belief that trying to appeal to security arguments β€” bio research is important because of national security, we need to be very concerned about misuse etc β€” aren’t going to work.

I know this is obvious, but if one does not believe in germ theory, as the secretary has stated, one does not need to worry about germs. The biological threats he is worried about come from medical interventions. If you’re healthy, in his mind, you don’t need those. (Soft eugenics)

I was horrified to realize that the argument that death was expected because of β€œunderlying conditions” (used w COViD and measles) was being used to justify starving children. Every child has the right to food and to not die of a vaccine preventable illnessβ€” why be against protecting the innocent.

The @nytimes.com , @washingtonpost.com & the rest treat #RussellVought like he's a run-of-the-mill small government conservative. The man is a religious zealot that wants to bring down the state & replace it with an American theocracy out of Margaret Atwood. It's the biggest story no one is telling.

This is beyond bad. All of our disease defenses are down now. We are sitting ducks. This is #RussellVought #DonaldTrump. They are endangering American lives with their insane crusade. These men are hazardous to your health and dangerous to the republic.

The Monovalent Mirage A pretend alternative to the MMR exists, just ask Andrew Wakefield

I wrote a thing about how this split the MMR up into monovalents is bullshit that Andrew Wakefield cooked up. It will be used to strip access to the MMR.

The MAHA movement continues to destroy public health.

This ostentatious Christian with the big cross around her neck is really saying that people who cannot prove their citizenship in an emergency room should be left on the sidewalk to die. And that's what she believes.

I think discrimination based on β€œkaryotype” is just baseline for them. And prob extends to all other karyotype variations.

Sloopy the cat wonders why anyone thinks that RFK Jr or Trump know anything worth knowing about autism vaccines or Tylenol

Another great analysis of what is likely coming out of ACIP. Must read (also, RFK Jr. must resign.)

Considering the decimation of cdc, nih grants halted, embrace of pseudoscience, and antivax actions that will leave the US unprepared for an H5N1 pandemic and may lead to the robust return of preventable childhood diseases, have you considered that grade inflation is a problem here?

He's an antivaxxer. People don't say things or do things like this if they aren't antivaxxers. He is not a skeptic, he just wants children to get polio.

RFK Jr.’s damage to the CDC is β€˜past the point of no return,’ Dr. Demetre Daskalakis warns β€œThe CDC you knew is over,” the infectious diseases doctor told The Advocate. β€œUnless someone takes radical action, there is nothing there that can be salvaged.”

there is no question in my mind that rfk jr is the most dangerous person in this administration and that his eugenicist ideology threatens the lives of millions of people www.advocate.com/politics/dem...

I mean, it is still the worst that they all worked together to end US leadership in S&T but 1. They will forever be tarred by it and 2. They are unhappy β€” so that’s something. 🫠

It’s hilarious that they have all have certainly heard that β€œif you want a friend in Washington, get a dog” and somehow didn’t think that would apply to them. And all the public whining? It’s not done and will continue to bite them in the future. So funny. Terrible people.

#NIH is hanging by a thread. The #CDC has been decimated. #RFK Jr. and Russell #Vought are psychopaths--I don't say this frivolously--they are cold, calculating, inflicting violence on millions through public policy. It is where we are right now. These men are not normal. 1/
