🏅 2026 top menace of the Fediverse

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'm kicking up one leg straight out, and smiling hard with my white teeth showing and my dark eyes bugged out behind my dark-rimmed glasses.
