Do you have a primary source for that? This sounds like a cancel-culture rumor intended to attach negative ideas to a person in order to discredit them.
After reading that entire post, I believe the above quote that:
"He thinks homosexuals are pedophile[s]"
is false. The rant asserts that homosexuals may be more predisposed to pedophelia and/or ephebophelia than those who are straight. Though as an astute commenter on the post pointed out that basically no evidence for the central thesis was provided by ESR.
He's a real winner. I won't go as far as to claim he thinks all homosexuals are pedophiles because I personally can't remember the link for when I read him say that, but here's a quote that edges that line:
And that brings us to the Jeffrey Epstein scandal. In particular, the widespread tagging of Epstein as a pedophile.
No, Jeffrey Epstein is not a pedophile. This is important. If conservatives keep misidentifying him as one, I fear some unfortunate consequences.
Pedophiles desire pre-pubertal children. This is not Epstein’s kink; he quite obviously likes his girls to be as young as possible but fully nubile. The correct term for this is “ephebophile”, and being clear about the distinction matters. I’ll explain why.
The Left has a long history of triggering conservatives into self-discrediting moral panics (“Rock and roll is the devil’s music”). It also has a strong internal contingent that would like to normalize pedophilia. I mean the real thing, not Epstein’s creepy ephebophilia.
Homosexual pedophiles have been biding their time in order to get adult-on-adult homosexuality fully normalized as battlespace prep, but you see a few trial balloons go up occasionally in places like Salon. The last round of this was interrupted by the need to take down Milo Yiannopolous, but the internal logic of left-wing sexual liberationism always demands new ways to freak out the normals, and the pedophiles are more than willing to be next up in satisfying that perpetual demand.
