This is complete and utter ignorance. Making fun of a person for a) who they are artistically. Even worse and more pathetically b) making fun of someone's disability. Finally the bottom of the barrel humor is c) Making fun a person who is deceased.
Moderate this comment as much as you want. I don't even care if you post or not it as long as it's understood that the person who created this gif was not clever in the slightest. Ian Curtis was nothing short of brilliant and a genius musically. It just so happens he was disabled during a time when little could be done to keep his disability at bay. Educate yourselves before making yourself look stupid.
