Liberal MP Adam van Koeverden called National Post columnist Rex Murphy a “national disgrace” on Tuesday over a column in which Murphy decried racism and discrimination. van Koeverden made the comments in a Twitter reply to Murphy’s latest National Post column titled “Why did Yale host a lecture called ‘The Psychopathic Problem of the White Mind’? “Vile trash. Rex Murphy is a national disgrace. Shame on you NP,” tweeted van Koeverden. In response to van Koeverden’s accusations, Twitter users called the member of parliament out for attacking Murphy for advocating against racism. Murphy’s column references an incident at Yale University where psychiatrist Dr. Aruna Khilanani gave a lecture in which she said that she fantasized about “unloading a revolver into the head of any white person.” “I had fantasies of unloading a revolver into the head of any white person that got in my way, burying their body, and wiping my bloody hands as I walked away relatively guiltless with a bounce in my step. Like I did the world a f**king favour,” Khilanani was quoted as saying.
