He didn't even specifically compare two killings in his original rant. Killing for food doesn't go on in fastfood restaurants, it goes on in abattoirs/slaughterhouses. People getting fed goes on in fastfood restaurants. So is he comparing people getting fed meat to the Norway killings? Nitpicking I know, but for someone who clearly regards himself as some sort of verbose genius, you'd think he could express his argument better.
Also, if he regards humans and chickens as equal, referring to Kentucky Fried Chicken as 'Kentucky Fried Shit' doesn't exactly make sense either. Who refers to the things he's trying to protect/represent/beat his chest for as 'shit'?
Well, if his aim was to be scorned by the world at large and regarded as an insensitive hypocritical dickhead, mission accomplished.
