Every educated and intelligent person glories in the freedom of women in Western societies to exercise their talents to the full, and their freedom to walk safely in the streets of our great cities.

So what are the enlightened minds of the Left to do when news comes of revolting assaults on women in front of Cologne Cathedral, one of the jewels of European Christian culture in one of Germany’s proudest cities? And how are they to react when growing evidence suggests that at least some of the culprits are newly arrived migrants from the Muslim world?

With mumbled embarrassment and nasty jibes against those who have long opposed uncontrolled mass migration, that’s how.

As an illustration, I had a radio clash with the Guardian writer Gaby Hinsliff on Friday after she admitted that ‘liberals like me are reluctant to talk about it’. While rightly chiding her own side, she couldn’t resist dismissing opponents of mass migration as dinosaurs and their views as ‘frothing rage’. Here is the news, Ms Hinsliff. Those who for many years warned against non-selective mass immigration (and were dismissed as bigoted dinosaurs by people like her) were concerned about just this sort of problem.
