The Star Wars fandom is approaching 50 years old, there’s been a lot of time for division to take place. Off the top of my head, in chronological order, there’s:

SW vs ESB
SW and ESB vs ROTJ
The OT vs TPM
The OT vs the PT
The Lucas Saga vs the Saga+EU
Lucas vs Disney
The EU vs NewEU
The Lucas Saga vs TFA
TFA vs TLJ
TFA+TLJ vs TROS
Episodes 1-8, the Old EU, the NewEU, the Holiday Special, Jaxxon, The Bigger Luke Theory, Every Fan Film, etc… vs TROS

So yeah, the fandom isn’t so much a unified group so much as it is a loose confederacy of groups with precious little to unite them.
