this is at least the second time (that i'm aware of) that the administration has directly referenced far-right /pol/ memes (the other being the Little Dark Age fashwave edit they put out a few months ago).

aside from the obvious reference to "Ein Volk, ein Reich, ein Führer" in the caption, "Remember who you are, [white man]" has been a catchphrase used over extremely similar edits like this one (note the tags on that entry...)
