"Yes, again, the being which he knows is stoling all light in the world, trying to merge it with Twilight (plot of the game); he would just sit there and stare at him. Again, he thought the light would hurt him, but didn't."
Why would Zant believe that Lanayru's ambient light would hurt him when even the Shadow Beasts can survive that without problem? Not to mention, your point was that the way Lanayru's light behaves in that scene is realistic, yet he doesn't do anything there.
"When Zant made him appear again, the light then hitted Midna and she was almost killed."
Difference between Midna and Zant is that Midna was actually touched and encompassed by the light.
"Nor can it be manipulated without the use of mirrors, gravity or electromagnetism. Are we going to say Kizaru has those last two?"
There's a difference between generating light and making light do things light cannot actually do. Just like there's a difference between a simple "shooting fire out of my hands" and "shooting fire out of my hands that is capable of freezing objects and healing people". One is clearly not real fire.
"And again, the Light Tears are not exactly physical."
They aren't, but they can be held physically, which is what I was saying.

"Fiction. Being able to possess the ability to fire light from one's fingertips doesn't make the light irrelevant due to it being unrealistic."
See my thing above, about the fire manipulator.
"Stating that it was an omnidirectional light is an assumption; we see it moving in only one direction and not shining over the walls on the other sides."
Omni-directional for all practical intents. It goes to the sides to hit the wall, and straight forwards to go outside the cavern. They couldn't have jumped up, otherwise they would've hit the tree brush and we would've seen them. They couldn't have dodged to the side, otherwise the would've been hit. And they couldn't have dodged backwards, otherwise we would've seen them again.
"It was really fast lightning, not slower characters."
In that case, how do you prove that Batman isn't MFTL+ for reacting to MFTL+ characters? I can just keep saying that X thing was actually MFTL+ in speed over and over again. This is an unfalsifiable argument you're making.
"Fiction. Also, huh?"
You can't just keep saying "Fiction" over and over again. Like the above fast lightning thing, it's unfalsifiable. Akin to saying "God works in mysterious ways".
