For Deleuze and Guattari, "becoming-minor(itarian)" is primarily an ethical action, one of the becomings one is affected by when avoiding "becoming-fascist".
They argued further that the concept of a "people", when invoked by subordinate groups or those aligned with them, always refers to a minority, whatever its numerical power might be.
Minority groups are defined by identities and are thus molar configurations belonging to the majoritarian State machine.
Kafka finds himself at home among neither the Prague Jews nor the dominant German and Austria-Hungarian power structure.
Each type of affective becoming marks a new phase of a larger process that Deleuze and Guattari call deterritorialization.
