Fascism, false nationalism and populism always use as one main sustain pillar is the creation of a group "escape goats", as a way to unite people(nazis vs jews and so on).
They are totally based on emotional feelings that drive the mob like, hate, fear, racism and group(s) ostracization as a form of control and bonding of the collective unconscious, and it is used as a mask to hide they no longer have rational solutions to solve problems.
"Fascism is not defined by the number of its victims but by the way it kills them." Jean Paul Sartre
