If the incident happened the way it's written (mages betrayed those that they raised up) and then hundreds or thousands of generations (cf players) have also passed and experienced similarly horrible fates (all of their, mage killed my family roles) that caused them to see the "practicing of magic" as the root cause, does that not make it more fact based rather than emotion and thusly logical?


*** Somewhat bad Real Life example ***
I know if cancer killed its first person 100,000 years ago (even if it was supposed to be a gift like John Travolta in Phenomenon / Original villagers) and continued to kill thousands of people as time passed, then it would be wholly logical to detest and hate it and even form groups designed to eradicate it (cancer research centers and highly specialized hospitals / Battle Cabal) no matter how many people may have benefited from the treatment (big pharma / Mages).
