You really don’t understand?
HATE does not sell well.
HATE is not usually a good tool to indoctrinate.
It’s too open abrupt and vulgar, in most cases anyways.
You sell the acceptance, you sell the image, you sell what the person is looking for, then you slowly bring them into the HATE, little by little in unassuming bite size pieces.
Dress it up as harmless at first until you have finished painting the picture in their minds that you wish them to see, once you have done that, then they will accept the HATE.
Even Hitler had to begin by spoon feeding it at first.
