The Nazis are far from extinct.
The rise of the ultra-right across the first world shows that relatively clearly.
You have it in Britain, in Italy, In France, in Spain and in more European countries and Lord knows you have it in the States!
It renewed its public face with the onset of the Middle Eastern and African civil commotions and the resultant refugees, because it finally had a tangible fact that all but the wilfully blind could not avoid seeing: the changing face of the city streets and the people trying to ride trucks and trains and boats and well, probably not 'planes, to cross into Europe. In France, those refugees wise enough to know that the UK is an even softer touch, with thousands of liberal whites screaming against scanning uninvited guests, did and still do their best to get across the Channel into England. An added advantage they have is the already huge population of non-whites, a diaspora of black and brown within which all who enter illegally have little trouble disappearing, and then re-emerging with brand new identities, should they so desire, rather than stay "invisibly lost" in the crowd.
In France, at the ferry terminal ports, some locals feed these people and encourage them. Of course they do! The better their health and the fitter they are, the sooner and more able they will be to get the hell out of France and into the UK! There's nothing humanitarian about it - it's clear self-interest in moving their problem next door.
No, one cannot deny them their right to want a better life; one can deny them the ability to drop in uninvited. Recent stirs about London no longer being a "British" city, as in a white one, shows just how divided the country has become, with those with poor sight (alluded to above) chanting that 'tis not so, despite the evidence that those who live there see every day.
Unfortunately, that has all beome entangled with the idea that Brexit will supply the solution, when in fact it is totally irrelevant, as anybody who has looked at it coldly, knows. Refugee rights are limited to the first safe state of entry, so they are legally obliged to stay, for example, in Turkey, in Italy, in Greece or even Spain. They don't ride an inflatable from North Africa along the Atlantic and onto British beaches!
They clearly have no intentions of staying where they first hit "safety".
It's a deep problem, and I honestly believe it's going to end in those forseen rivers of blood.
