Leftists against homosexuality? How can this be?

I suppose if you are a Gay Left Marxist theoretician you can't always choose your allies.

NEPAL'S hardline Maoist guerillas, on the brink of achieving effective government power in the Himalayan kingdom, have turned their attention to so-called "social pollutants" and denounced homosexuals as "a by-product of capitalism".
Emerging from a decade of fighting government forces, the insurgents have launched a clean-up drive against polygamy, polyandry, infidelity, drunkenness and homosexuality — even though many gays were previously aligned with the Maoists against the autocratic rule of the widely despised King Gyanendra.

Maoist cadres, seen regularly on the streets of Kathmandu as they move towards taking over key roles in the Government under a peace accord worked out with Prime Minister Girija Prasad Koirala, have warned home owners not to let out rooms to gays and lesbians.

They have also announced "a zero-tolerance policy towards homosexuality" and a crackdown on pornographic films.

A Maoist commander allegedly told a group of gay men: "We are against any aberrant activity that could have a negative and vitiating effect on society."

Does Andrew Sullivan know about this? Or is he too busy worrying about "Christianists"?
