I bought a Blue Light Germicidal Light Bulb, 405 nm blue light. Read about safety for humans, and its germicidal properties. Not as powerful as UV light in general, but safe for humans. Not as powerful as far UVC but much cheaper: $20. Anyone tried it? amazon.com/dp/B08FCW3ZCL

Serbia just voted out the party that held power for 14 years under authoritarian rule. People organized, showed up, and won. America, this could be us next week!

AHORA - sábado, 24 octubre, Operativo de los #Terroristas de ICE en Capetillo, RÍO PIEDRAS _ Agentes de ICE se llevaron a gente de nuestra comunidad. Al recibir el aviso, compañeras de la Colectiva salieron en defensa de los ciudadanos. Fueron agredidas por agentes DHS, les apuntaron con tasers y latas de gas pimienta industrial en las caras. También hubo agentes que se bajaron apuntando con armas largas para removerlas de la calle. El suceso ocurrió en la calle Arzuaga, con la Avenida Barbosa (frente al letrero del Colegio San Antonio). #FueraICE #PuertoRicoNews #jimaguanews #PuertoRico Fuente: Colectiva Feminista en Construcción

Next "press" conference:
White House Communications Director Steven Cheung thinks that Nicki Minaj would be a great Press Secretary. If we thought the Administration was a freaking circus before image with her there.

It's fucking crazy that an investigation exposing how Jared Kushner laundered billions if dollars through Azerbaijan, including payments to a warlord, a mercenary, and a hitman, isn't getting more attention.

Trump is now talking about Nicki Minaj’s “one hell of a beautiful ass”. This is how the country has fallen. This is sexual harassment.

Congratulations to Lula on his extraordinary reelection victory in the Brazilian presidential election. Lula has stood up for Brazilian workers & democracy — and will continue to do so in the next four years.

Fox News is putting Nicki Minaj up telling people to vote red. Let’s break that down. Can Nicki Minaj vote? No. She’s not a U.S. citizen. Can Nicki Minaj’s husband vote? No, he’s a registered sex offender. Can Nicki Minaj’s brother vote? No, he’s serving 25 years to life for child sexual assault. She seems like the perfect spokesperson for MAGA republicans.

Y’all. We are literally witnessing a coup attempt going on live in Brazil. Bolsonaro is losing the election badly, so his people in state and local leadership are grounding flights, canceling public transportation going to Lula strongholds. Massive voter suppression. Supreme Court had to intervene to mandate 2hrs extra at the polls. Mixed reports on how many polling stations are respecting the ruling. Whew!

"Están siguiendo órdenes." Nazis de mierda.
estoy seriamente tratando de entender la consigna que repiten una y otra vez para justificar el abuso de ICE en las comunidades dominicanas en Puerto Rico: <<están haciendo su trabajo>>. Para esta gente, ¿violentar los derechos humanos es parte del trabajo del gobierno? ¿?¿?¿?¿?

No quieren ser Khuva, pero tenemos una dictadura de corruptos que traquetean con las elecciones, le entregan el país a mafiosos millonarios y lo tienen sumido en apagones, inflación, desempleo y sin servicios básicos. ¿Se sorprenden con la violencia? No han visto nada aún...
