Plain sight.
Quoting a recent article in the critic about a 1978 interview with Foucault:
^There he argued that it was “quite unacceptable” and an “abuse” to assume “that a child is incapable of explaining what happened and was incapable of giving his consent” to sex with an adult. (Note that Foucault takes it for granted that the child will be a boy.)
It is a matter of public record...that Foucault signed a petition to the Assemblée Nationale in 1977 calling for the decriminalisation of all “consensual” sexual relations between adults and children^
From The Times article:
"They were eight, nine, ten years old, he was throwing money at them and would say ‘let’s meet at 10pm at the usual place’.” This, it turned out, was the local cemetery: “He would make love there on the gravestones with young boys. The question of consent wasn’t even raised.”
