Well I'm not sure this counts but it's kind of positive and there's a good report of it on the Ekklesia website titled Archbishop of Canterbury says churches must be 'safe' for gays.
There is also further discussion on the Thinking Anglicans (is there any other kind?) website.
Some of the quotes are quite interesting as he appears to say that apart from churches being safe places for "gay and lesbian people" he also appears to both criticise certain Provinces who are actively in support of oppressive measures, notably in Nigeria, although he underlines the presence of hate crimes even in Western countries.
His support for the "proper liberties [freedom of association, assembly and expression perhaps?] of homosexual people" is clearly very important. You can see his statement here.
Here's a chunk of the statement (I underlined some bits):
“ The commitments of the Communion are not only to certain theological positions on the question of sexual ethics but also to a manifest and credible respect for the proper liberties of homosexual people, a commitment again set out in successive Lambeth Conference Resolutions over many decades. I share the concerns expressed about situations where the Church is seen to be underwriting social or legal attitudes which threaten these proper liberties. It is impossible to read this report without being aware that in many places – including Western countries with supposedly ‘liberal’ attitudes – hate crimes against homosexual people have increased in recent years and have taken horrifying and disturbing forms."Just timed right for the release of the Yogyakarta principles - let's hope he's willing to sign up.
And while on the subject of the Yogyakarta principles I was pleased to see this article on the Comment is free (Guardian) site - Righting wrongs with some interesting discussion of how in previous UN debates countries who do not exactly have a shining record of human rights managed to block and vote down the Brazilian resolution on sexual orientation.
