"Esistono senza il consenso di nessuno. Sono odiati, braccati e perseguitati. Vivono in silenziosa disperazione tra il sudiciume. E tuttavia sono in grado di mettere in ginocchio intere civiltà. Se sei sporco, insignificante e senza amore, allora i ratti saranno il tuo modello." Banksy

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.
