Mass deportations were a sad but not uncommon operation at the time, as seen for example by this Churchill speech from 1937:
>I do not admit that the dog in the manger has the final right to the manger, even though he may have lain there for a very long time. I do not admit that right. I do not admit, for instance, that a great wrong has been done to the Red Indians of America, or the black people of Australia. I do not admit that a wrong has been done to these people by the fact that a stronger race, a higher grade race, or, at any rate, a more worldly-wise race, to put it that way, has come in and taken their place. I do not admit it. I do not think the Red Indians had any right to say, “The American Continent belongs to us and we are not going to have any of these European settlers coming in here.” They had not the right, nor had they the power.

Or this one from 1944:
>Expulsion is the method which, so far as we have been able to see, will be the most satisfactory and lasting. There will be no mixture of populations to cause endless trouble, as has been the case in Alsace-Lorraine. A clean sweep will be made. I am not alarmed by the prospect of the disentanglement of populations, nor even by these large transferences, which are more possible in modern conditions than they ever were before.

The absurdity comes when they're used to try to conjure up a boogeyman.
