This arc has really proven that so many people don’t know how to let old theories die. Such as:
Shanks secretly being evil
Harald being Kaido’s dad
Xebec being Buggy’s dad
Revs/BBPs attacking MJ
HKs not being a secret
Kid still being alive
Yamato joining the crew in Elbaf
Urouge showing up in Elbaf
Big Mom showing up in Elbaf
Usopp wielding Ragnir
Roger being top 1
Shiki being important to the plot
Powercreep not existing
All of these got disproven (or at the very least became very implausible), but people keep parroting them for some reason
