From the interview I shared a couple of days ago:

In the absence of anything better, I shall support the program of the Socialists. I recall something (Roland) Barthes once said about having political opinions ‘lightly held’. Politics should not subsume your whole life as if you were a hot rabbit.

Jamin Raskin, “A last interview with French philosopher Michel Foucault”, City Paper, Vol 8 No 3, Jul 27-Aug 2 1984, p. 18.

A ‘hot rabbit’ is a rather literal translation of what was presumably ‘un chaud lapin’, a sexual expression for which ‘rabbit in heat’ might be more appropriate.
