>>509529739 (OP)If you go on the /x/ archives the first time Blue Eisenhower November was ever posted was on December 18, 2017. It was in a response to OP talking about another thread that got deleted in which the OP of that thread was talking about how we live in a simulation and that god created the simulation and us in order to perpetuate himself or something. I don't fully understand it. I don't know why the person responded with blue Eisenhower November, but that's the earliest mention I could find of it anywhere. Blue Eisenhower November has something to do with the simulation, I'm not fully sure what though.
