There's nothing wrong with Luke saying "laser sword."

I keep seeing people upset about this as if Luke doesn't know what that it's called a lightsaber. Or at least that Rian Johnson didn't know that or, somehow, nobody told him..In universe, there are lasers and there are swords. These aren't new words for them. It's so obvious that Luke was being facetious when saying that because he was trying to convey the silly idea of facing a military force alone. He wasn't dignifying the idea with proper terminology.I just feel like I'm taking crazy pills because this is such a weird thing to not understand. via /r/StarWars http://bit.ly/2I9IhVx
