@Canopus Your post articulated a lot of my own thoughts about TLJ, and your explanation of Star Wars as modern mythology filled in some gaps in my own thinking.
Modern mythology is exactly the reason TLJ is so divisive with the fanbase. Mythology is an important aspect of cultural identity. Even small variations in mythology can be divisive for a culture. For some people, TLJ violates their perceptions of the mythology, and this threatens their cultural identity as a fan. For other people, TLJ is a natural expansion of the mythology, or a welcome alteration, and they feel gratified rather than threatened. These differences are factionalizing the fanbase.
For Star Wars fans this has happened before. The scale and stakes are more severe this time because the dispute is over a new saga film. Forums like this one are battlegrounds of sectarian violence, with extremists trying to shout loud enough to be the only side anyone can hear or agree with.
