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.
