Philosophy cafe, what's the most controversial idea you cannot discuss with most people? Discussing controversial ideas, the goal is not to have long night debates, which are exciting but can also be exhausting.

Everyone gets 5-10 minutes to present a case of something weird and fringe but something they researched and can build a logical case. It doesn't have to be a strong case you fully believe in; weak, loosely held opinions on something you find interesting and at least probable are totally fine to present as long as you explain your weak argument position honestly.

The idea of the philosophy café is to hear as many interesting and fringe ideas as we are usually not exposed to and learn how to build up a case for controversial ideas.
