Marx in particular commented rarely on sexuality in general. Writing for Political Affairs, Norman Markowitz writes: "Here, to be frank, one finds from Marx a refusal to entertain the subject, and from Engels open hostility to the individuals involved".[8] This is because in private Engels criticized male homosexuality and related it to ancient Greek pederasty,[9] saying that "[the ancient Greeks] fell into the abominable practice of sodomy [Knabenliebe, meaning "boylove" or pederasty] and degraded alike their gods and themselves with the myth of Ganymede".[10] Engels also said that the pro-pederast movement "cannot fail to triumph. Guerre aux cons, paix aus trous-de-cul [war on the cunts, peace to the arse-holes] will now be the slogan".[11] Engels also referred to Dr. Karl Boruttau as a Schwanzschwulen ("faggotty prick") in private.[12]
