I think PC is used as a tool to close down arguments, and as a form of self-censorship. As mentioned above, liberal elites are Obama/Clinton/Fabians/EU mafia, etc, but they are not really liberal they are commies. Their vision is for a one world government run for the bendfit of the elites and the corporations/banks. You can see how jobs have disappeared from the West, secretive trade deals are being negotiated, migrants are flooding in, and people are feeling disenfranchised. This all all by design as the aim is to break down countries and their cultures. You might have also noticed increasing surveillance and a creeping militarisation of the police. Depending on who you ask, you may get differing views about what the future has install for all of us.
