How do I know Lightsaber blades stop at about a meter length? Real lasers don't, No character ever says that it is so.

There is an annoying 10-year old kid in Episode 1 that uses the word "Laser Sword" the first time he sees a lightsaber. Nobody else does it. It isn't a laser just because a 10-year old kid who does not know better says that it is.

I actually think you're agreeing with me.

Since NOTHING in Star Wars called a laser acts like a laser ("that wasn't a laser blast, something hit us!") worrying about what a real world laser does seems unnecessary.

Whatever they are, it seems best just to take them as presented as presented in the films.
