although it may have appeared as such, that was not an attack -
consider the following analogy:
you go into a room with Wolverine fans and proclaim that Wolverine doesn't really need his claws; now, regardless of whether or not you may have a point, odds are high you'll get laughed out the room, as many feel the claws are an integral part of his character.
and i make that coming from the perspective that the jedi way did not fail and kindly direct you toward the jedi code below...
when doing so, you can see luke obviously transgressed (lack of training?) when he rose his saber to kylo - which, is truly counter to the person previously established in three movies and adored by generations ........... not completely unheard of that he would digress so much, i guess, but i've already gone down that route from a production standpoint.
There is no Emotion, there is Peace.
There is no Ignorance, there is Knowledge.
There is no Passion, there is Serenity.
There is no Chaos, there is Harmony.
There is no Death, there is the Force.
there are core tenants of of stoicism and buddhism in there and if you can fundamentally improve on those two schools of thought, i highly encourage you to go start a church and prep mantle space for your nobel prize.
listen, as i had alluded to previously, i'm just simply choosing to get off the star wars train, and have no ill-will, grudge, or lost respect for those continuing to ride - may the force be with you (but is there even anyone left in the galaxy that knows what that truly means anymore?... argh, sorry)
