You're told it'll sabotage your career if you're a vocally politically opinionated, queer, woman. But things sabotaging my career are systemic xenophobia, sexism, and horrible job market. Which are a direct consequences of people not being vocally opinionated in the first place.

People are struggling. I want us to think about how we're going to help each other hang in there this winter. How are you going to support your friends, co-strugglers, and community as they push through this moment? How can you help people muddle through, materially and/or emotionally?

🧵Spotted at a Christmas Market in Aotearoa New Zealand:
A tiny human is aghast at Mum's suggestion that she needs a nap.
Shaking her head vehemently, she roars: "I'm NOT sleepy!"
Mum sighs, agreeing that she is indeed not looking tired.

*popular in the sense that I foresee this being protested out of existence by the gateway communities that in many case are, ironically, MAGA-majority.

This is called “chain refoulment” and it’s illegal under both U.S. and international law. And the State Department and ICE know very well what Ghana is doing and simply don’t care.
ICE deported a woman who owned a home in the US for 30 years. A judge banned ICE from deporting her to Sierra Leone where she had been tortured, so it deported her to Ghana, which kidnapped her and sent her back Sierra Leone anyway. ICE is part of this illegal conspiracy.

Dusty hurt his paw about a month ago. We took him into the vet and x-ray showed nothing was broken, but he hasn’t been able to walk on it since.
This morning, I got up early and took him back to the vet. We’ll see what they discover.
This photo is from a while ago before he was hurt.

Just a friendly reminder as we go into the holidays:
Folks don't have to explain to you why they don't drink.
If you offer them a drink and they decline, don't ask them why. It's not your business.
Just offer them something without alcohol to drink instead. And move on.

A very easy solution is to make a lovely punch. Put a bottle of rum on the side for people who want it alcoholic.
Same with eggnog.
I mean have other stuff too but a lot of classic holiday beverages are really easy to just do non-alcoholic as the default.
