Orwell on nationalism and Einstein on patriotism

After Theresa May's own goal and anticipating chaos among Brexiteers (with the UKIP replaced in influence by the heirs of Rev. Paisley) in the UK and similar movements in other places, I thought it could be of interest to remind the reader about what two of the brightest minds of the past century had to say about patriotism and nationalism:
-Albert Einstein said that "He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would fully suffice. This disgrace to civilization should be done away with at once. Heroism at command, senseless brutality, deplorable love-of-country stance, how violently I hate all this, how despicable and ignoble war is; I would rather be torn to shreds than be a part of so base an action!"
 -George Orwell, in a long article said among other things that "By ‘nationalism’ I mean first of all the habit of assuming that human beings can be classified like insects and that whole blocks of millions or tens of millions of people can be confidently labelled ‘good’ or ‘bad.’
And, "Indifference to Reality. All nationalists have the power of not seeing resemblances between similar sets of facts. A British Tory will defend self-determination in Europe and oppose it in India with no feeling of inconsistency. Actions are held to be good or bad, not on their own merits, but according to who does them, and there is almost no kind of outrage — torture, the use of hostages, forced labour, mass deportations, imprisonment without trial, forgery, assassination, the bombing of civilians — which does not change its moral colour when it is committed by ‘our’ side. The Liberal News Chronicle published, as an example of shocking barbarity, photographs of Russians hanged by the Germans, and then a year or two later published with warm approval almost exactly similar photographs of Germans hanged by the Russians. It is the same with historical events. History is thought of largely in nationalist terms, and such things as the Inquisition, the tortures of the Star Chamber, the exploits of the English buccaneers (Sir Francis Drake, for instance, who was given to sinking Spanish prisoners alive), the Reign of Terror, the heroes of the Mutiny blowing hundreds of Indians from the guns, or Cromwell's soldiers slashing Irishwomen's faces with razors, become morally neutral or even meritorious when it is felt that they were done in the ‘right’ cause. If one looks back over the past quarter of a century, one finds that there was hardly a single year when atrocity stories were not being reported from some part of the world; and yet in not one single case were these atrocities — in Spain, Russia, China, Hungary, Mexico, Amritsar, Smyrna — believed in and disapproved of by the English intelligentsia as a whole. Whether such deeds were reprehensible, or even whether they happened, was always decided according to political predilection."
