We're talking about a space fantasy where combat in space is a re-enactment of aerial combat.Why are light sabers portrayed as impalement weapons?
When Maul stabs Qui-Gon, he "freezes" in shock as Maul pulls the blade out, and then Qui-Gon falls.
Same with Reva in OWK, when she impales the Grand Inquisitor.
Same with Vader on the rebel soldier in Rogue One (when he impales him through the door)
Realistically, the aggressor would not have "slid" the blade out of the victim along its path to remove it as you would with a sword or spear... they would have completed the slash through the side of the body to remove it (or just turned the blade off).
And the saber is not a pole that will support the victim's weight while they are standing there. As the victim, you would fall in some direction against the blade, which would slice through your side.
Makes sense that "laser swords" are also treated like imitations of regular ones.
