That is Hail, not Heil
That is Hail Trump as in Hail Caesar Augustus, not Heil Trump as in Heil Hitler.
This is a reference and reverence to God Emperor Caesar Augustus who did to decadent Roman democracy much what Hitler did to decadent German democracy for much the same reasons, but fortunately your average Harvard graduated social justice warrior does not know any history other than Hitler killing the Jews, whites enslaving blacks, and that every thing was invented by blacks except what was invented by women.
That is why we call him God Emperor Trump, not der Führer.
By the way, the Roman salute to God Emperor Caesar Augustus differs slightly from the Nazi salute, in that the palm is visible, rather than down, and the fingers may be semi closed, but not clenched, but don’t try it because social justice warriors will not know the difference.
We are who we are, so to salute president elect Trump in the hope that he will soon become God Emperor Trump, I recommend the military salute universally used by western armies for a long time. For extra fun points, this salute was in fact the salute used by the German army in World War II, and every other white army, but social justice warriors don’t know that.
