This screenshot is taken from South Park’s season 12, episode 5, which (in my comprehension) is a parody on the identity confusion of Mr/s, Garrison, due to the growing impact of genetic enhancements on transsexuality. Braidotti asks if transsexuality is a dominant posthuman topos, and we could add that:
1) posthumanism examines the modes that technological enhancements change the ways people percieve their own identities, surpassing the old gender barriers based on traditional understandings of normality;
2) biotechnological enhancement reveals the everyday self as a multiple personality (De Mul 2010: 171).
That is why Mr/s Garrison is allowed to “play” with its own gender identity, but therfore becoming the object of parody of South Park’s creators. Maybe they are expressing their conservative stands on this topic, but they are definitely showing how these enhancemets influence the identity experimentations, that sometimes overwhelm us.
