I honestly think this is the branching off point for the two parallel universes, both have equal numbers of memes but the World Is Never The Same, Shaped In Ways We Cannot Imagine
I feel like the death of a child is not something people are above making jokes about and for some people might be even more inclined to make jokes. it is hard to put measurements on though
Really, I do see this as a breaking off point. What if there was that world? Would we shut down zoos? I think it honestly could have been a turning point. Memes would exist in both worlds tho
