"YOU DARE BRING LOGIC TO MY LULZ? YOU MUST DIE!!!"
More seriously... calm down, Marinus. It's just a silly joke. An Internet meme. I can't believe you've never encountered it.
The original line was from a farily stupid custcene from a Zelda CD-i game:
"YOU DARE BRING LIGHT TO MY LAIR? YOU MUST DIE!!!"
Watch the cutscene here:

It's incredibly funny

and now people joke about it. You will understand why if you watch the video.
I can make tons of these if I want to.
"YOU DARE BRING LIGHT (YAGAMI) TO MY LAIR? YOU MUST DIE!!!"
"YOU DARE BRING GLITCHES TO MY PROGRAM? YOU MUST DIE!!!"
And so on. It's stupid but it caught on.
EDIT: Here's an example of a joke based on this meme:
10 things you shouldn't take to Ganon's lair
