Since I'm also in the never banned club, the most controversial thing I ever said on Reddit, based entirely on community reactions, was probably "americans perceive everyone outside america as sub-humans who are beneath self-determination, like they should be the ones to choose how we do everything".
Sounds like at least among lefties this should have been an uncontroversial statement, but gods I made some gringos mad on that day.
Yeah I'm kinda used to it. As said before, in my country (Brazil) the power grid is... It depends on which state you are in. It's 120 in my state, but directly south of us is one that uses 240, and to the north two that use 120. I'm used to reading labels and flicking voltage switches.
