There is a reason behind the leftist refusal to compromise.
Previously the left were able to talk freely, to exchange ideas with other parts of the left or even the right. Then along came The Frankfurt School and its uncompromising idea of political correctness.
This thinking, that some ideas are politically more correct than others, was tested out in Maoist China. It worked well there.
And so it was brought to the West via academia and the education of children.
And now we have the most bigoted worldview masquerading as a drive towards peace and love. This is not what these people want. If they did they wouldn't attack people with dissenting views or riot at the slightest provocation. They simply want their side to win.
Now, if you're opposed to unlimited immigration you're a 'racist.'
Now if you're opposed to those leftists who say they want to kill white babies because white people are the cause of all problems you're a 'White Supremacist.'
They have their ideas on identity politics and their minds are now full up and closed off.
We are stuck with them. It's almost impossible to deprogramme them as any information which conflicts with their position is deemed politically incorrect.
They are essentially mindless robots reacting to stimuli in a pre programmed way and I suspect that at some time in the near future normal people will have to defend themselves physically against these extremists.
