Why people wank Palpatine's lightsabre bend feat?
"Palpatine still made no move to defend himself from Skywalker; instead he ramped up the lightning bursting from his hands, bending the fountain of Mace's blade back toward the Korun Master's face."
-Revenge of the Sith
This is a metaphor meant to express how Palpatine was trying to disarm Windu with his Force lightning.
Do people really think he could actually bend a lightsabre's blade with his Force lightning?
And why is that?
And why is it impressive?
Is it stated somewhere that lightsabres can resist(and maintain their straight position) against lightning for an amount of time?
