This flower is called a Poinsettia in English. September is the best time to discuss the name's connection to colonialism and why I would never call this plant a poinsettia.

And here I am flabbergasted, that the OV has always had the Mexican National Anthem in the background in the gun shop scene?
Does anyone know why??

It drives me crazy that US journalists and commentators say stuff like "he was a white supremacist but his name was non-European: García". García is a Spanish name, brought to the Americas by Spain, a country in Europe. A fact the supremacist knows and embraces.

Lol Ah the made up world fascists live in... this is not a left-right issue. Everyone in the Spanish-speaking world sees América as a continent. In fact, several countries even use “estadounidense” (United-Statian). This is about history and cartography. Plus, before 1898 loads of Americans agreed

It’s tangential to his relationship with Epstein, but remember Jack Horner rose to fame by claim jumping Marion Brandvold. She found Egg Mountain and the baby Maiasaura, loaned them to Jack, and had to sue to get them back - returned in 2004.
