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 as a species. Kindness and empathy are the noblest of human traits.

No alt-text/slop alt-text = no repost.

Do not feed the trolls; block them.

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.
