>>Dugin’s first wife was Evgeniya Debryanskaya, who he taught English by reading the suspiciously queer The Picture of Dorian Gray.

Разве не ошибка писать "who he taught"? По смыслу, вроде бы, должно быть "whom".

'When in doubt, try this simple trick: If you can replace the word with “he”’ or “’she,” use who. If you can replace it with “him” or “her,” use whom.'
