Like in the British colonies they used to categorise you under various slurs depending on your ancestry white v Black and over generations it all got too difficult. Same with your binary gender and compulsory heterosexuality. The colonial game is up folks no matter how much you try to police it

Like with binary gender being extremely colonial they tried to be binary with race in the USA in particular and ended up with truly ridiculous one drop rules. Colonial categorisation of the breadth of human experience and box ticking has a lot to answer for!

Christmas zoned phlogopite in carbonatite for #ThinSectionThursday. In PPL (left) Mg-rich core shows less colour than brown rim (pleochroic to colourless) which has higher Fe, possibly due to Al-deficiency. Same chemical variation gives different interference colours in XPL (right) 🧪⚒️🌋🎄🎅
