@[email protected]100% artisanal, human-made bytes.
Anti-DEI is white supremacy. Black lives matter. LGBT+ rights are human rights. Healthcare, security, a decent income, and housing with dignity are human rights. Abortion is healthcare. Science is our best hope. Kindness and empathy are the noblest of human traits.
It can ALWAYS get worse.

I once worked with goats. I moved into tech.This was a mistake.
Expect sheep, wool, and textile history. Also birbs. Infosec on occasion.
I use content warnings for topics and images that can trigger PTSD. I do not use them to shield people ***without*** trauma from experiencing racism, sexism, transphobia, and other forms of discrimination. If you can ignore politics, you’re not likely in need of content warnings for much of anything, really.
