I have not seen “2016,” so I’ll defer to SmartMuffin’s description. In common usage it seems that “anti-colonial” and “anti-Western” are practically synonymous. It’s implied that because of the history of colonialism/imperialism in the 19th and early 20th centuries, Western countries have an ongoing moral responsibility to sacrifice their interests to benefit non-Western countries, in large part through a redistribution of wealth (foreign aid, debt forgiveness, etc.).
