I know I've asked people to explain mainly because I find the reasoning behind most people who ship Kurtofsky to be something like "aww, isn't Dave just a big teddy bear and it's adorable because Kurt will look after and hug him" and stuff like that. If shippers held Karofsky accountable for the fact that he threatened Kurt's life... I don't know. No matter the reason I know I'll NEVER ship Kurtofsky (If it becomes canon I'm just not watching Glee anymore. I find it that repugnant), but every time I've seen people ship it it's like the shippers are in some kind of fantasy world where it's like "aww isn't Dave ADOWABLE?" when all I see is a guy who threatened to kill Kurt. So sorry, I need some explanation.
