Recurring arguments in the field of migration: slippery slope, perverse effect, appeal to fear, " Godwin's law ", analogies, dissociation versus amalgam.
Ad personam and ad hominem arguments, the fabrication of an imaginary adversary (" straw man "), the degradation of public debate ; categories or insults ? (cf. Bourdieu on " categoremes "). When insults take the place of arguments (" immigrationnistes ", " identitaristes ", " communautaristes "...). The " judgement of madness " (Angenot), the judgement of high treason (against the Republic, France, national identity).
