I wasn't arguing that you can't swing a lightsaber blade quicker with more strength, if that's how what I was saying came off across, then that wasn't my intention. All I was saying is that how quickly you swing the blade has no relation on the damage the lightsaber causes on impact because the blade is weightless, and therefor can't cause any damage in that way; you can't channel speed and force into a weightless blade to inflict kinetic damage.
