Sylvain Lazarus worked out a theory of the social function of political categorizations (cf.
Previously, it was discussed at length by Alain Badiou in his Abrégé de Métapolitique (1998), now translated into English as Metapolitics (2005).
To quote Badiou himself, the UCFml is "the Maoist organization established in late 1969 by Natacha Michel, Sylvain Lazarus, myself and a fair number of young people".
[1] Fifteen years later, Lazarus was a founding member (along with Badiou and Michel) of the militant French political organisation Organisation politique [fr][2] which called itself a post-party organization concerned with direct popular intervention in a wide range of issues (including immigration, labor, and housing).
In addition to numerous writings and interventions since the 1980s, L'Organisation Politique has stressed the importance of developing political prescriptions concerning undocumented migrants (in France referred to as les sans papiers) and stresses that they must be conceived primarily as workers and not immigrants.
