Which is what exactly?
It is all this political correctness which we even see in the US. What was the centre ground in the 80's is now on the right and what was on the left is now centre ground. It is a reasonable idea gone mad; and used by the elites and ruling classes to control the mindset and dialogue of the masses.
We see the ultimate sickness of it in the Rotherham police who were more concerned about not being called racists than helping under aged teenagers and kids who were being sadistically raped by some Pakis. There are eleven forces being investigated for similar dereliction of duty and concern. We also see this in the students who almost went off crying like little children when Germaine Greer aired a point of view that clashed with theirs and called for her talk to be band, instead of debating against her viewpoint as responsible adults.
We only see some semblance of common-sense and level headedness, and strong vociferousness, against this kind of madness from people on the right in the Conservatives; not Cameron and those in the centre of that party, and UKIP. But when they do this they are accused as being racists etc., using all the techniques those Leftie peoples have learnt to try to close down the debate. There are intelligent people on the left now who are also waking up to the insidiousness of what has been going on and are looking to correct thing.
