Hatred, ignorance, fear, greed, and discrimination are viruses, magnified by suffering, carried in buckets, spilled onto the world.

We cannot eliminate them by actions that magnify hatred, ignorance, fear, greed, discrimination and suffering - only by actions that relieve them.

A big part of the authoritarian playbook is war. War takes over the news. War blots out criticism. War divides a nation’s people, subjecting those against it to being called unpatriotic. War grants leaders all sorts of emergency powers. War consumes everything else.

We mustn’t let this war do so.

The richest man owns X.

The second and third richest men control Google.

The fourth richest man owns Facebook, Instagram, and WhatsApp.

The fifth richest man owns The Washington Post.

And now the sixth richest could soon take over both Paramount and Warner Bros.

Totally agree. I believe there are a few articles showing good evidence of this also in vaccine responses.

Mapping the specificity of H3N2 strain-specific and cross-reactive human neutralizing antibodies elicited by the 2025-2026 influenza vaccine An H3N2 variant, named subclade K, continues to circulate widely during the 2025-2026 influenza season. This virus possesses a hemagglutinin (HA) protein that has eleven substitutions relative to the ...

Our preprint examining the specificity of human antibodies that cross-react with subclade K H3N2 viruses was posted this morning on medRxiv. These studies have implications on what vaccine strains should be selected for next year’s influenza season. 1/

Someone has sure already made this observation but the fact they can convert all those empty warehouses into prison camps means they could have converted them into housing, community centers, job training centers or, hell, libraries or schools all along. It’s always a matter of will not resources.

The people of Minnesota have executed one of the most impressive civil resistance campaigns I can remember:

- Organized a city wide general strike
- Maintained nonviolent discipline amidst violence
- Mobilized 10,000s in subzero temps to protest and watch ICE
- Flipped public opinion against ICE

A reminder to the news media: β€œconflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.
