LIBERTARIANISM IN A NUTSHELL. Ronald Bailey at Reason:

Brendan O'Neill, the editor of spiked, writes a furious and fascinating book review asserting that some neo-Malthsuian progressives are valorizing homosexuality as eco-friendly. Why? Because gays and lesbians are less likely to have children and children despoil Mother Earth.

Evidence offered: An old Anthony Burgess novel, a self-evident joke by George Monbiot, and... Paul Ehrlich. Seriously.

Pop over to his source, and you find that innocuous statements like "in an overpopulated world, it would be a good thing if there were more homosexuality," and the existence of "Cats Not Brats" t-shirts, are taken as threats by some shadowy legion of homosexual supremacists. (Similarly, I suppose, those ladies' t-shirts that say "BITCH" are signaling devices for gynocrat terrorists.)

Bailey sums up:

O'Neill is not objecting to gay sex nor to choosing to have no children, but against polticizing those lifestyles as being morally superior on ecological grounds. The implied concern is that asserted moral superiority could be translated into coercive public policy.

Yeah, that's what we should be worried about: Coercive pro-gay policies.

It's like when they defend banks against their would-be regulators and the rich from paying more in taxes -- In fact, it's what libertarianism is all about: Bravely defending the powerful from persecuted minorities.

UPDATE. Thanks to commenter Jeffrey Kramer for doing the hard work:

If you're playing buzzword bingo, O'Neill's piece has the "chattering class" of the "liberal elite" (aka "elite elements," aka "our moral betters" aka "the supposedly liberal and tolerant") which breakfasts on "muesli" while "feverishly" contemplating overpopulation, encouraged by Psychology Today, which is "the bible" of the "medical elite" and also by "the upper echelons" of the gay movement, who are "their self-styled" representatives, while drawing back in horror at "the baby-making masses" and employing "trendy-sounding" arguments from ecology to help establish a "morality police."

Oh, well, when you put it that way...
