The Rebbe teaches that the Jewish people have real freedom of choice

A gentile has absolutely no freedom whether to love or hate a Jew; nowhere is this more evident in the simple fact that the same people who caused untold – beastly – harm, murdering hundreds of millions of Jews (or some high number like that – considering that in the Temple Times there were already millions of Jews and the holocaust was one of  many holocausts in our history to murder every third Jew in the world) so these same christens Eisav have now made a round about turn and did a 360, in fact there are far greater supporters of Israel in a certain respect among evangelical Christians – an absolute miracle considering Christianities millennia (that’s thousands of year history) of persecuting Jews.

So the only thing we have to fear, is fear itself.
