This allegation was invented by a dude called Guy Sorman. He later took it back when presented with evidence that this was a rumor entirely of his making.
I suggest people Google Sorman before repeating his completely unverified claims. He’s a globalist fanatic who despised Foucault’s early opposition to neoliberalism.
Foucault was absolutely promiscuous with young Tunisian guys but this whole thing about him having sex in cemeteries with 8-year-olds came from one envious competitor.

Most gay men who traveled to Tunisia seemed to be having sex with very young boys, tbh, so I’m still side eying Foucault. But the graveyard story was always very over the top. I will investigate
