It won’t occur in America due to demographics and population density but Europe without a doubt a purge will happen. Firstly with the Muslims and secondly with Blacks. Europeans cannot deal with the ever increasing fact that political and economically as a bloc they are declining. It just isn’t in their nature to be NOT dominant, as it shocks their core value of them being superior to everyone else. Europe’s eventful decline will mean danger for all non-Europeans in Europe. Non-Europeans forget that few decades ago Europeans were slaughtering each other and genociding brown/black people worldwide, much hasn’t changed. All it takes is a complete economic meltdown for the right to seize power and hooligans will start cracking skulls.
