Just to show what a late-comer I am, I'm linking to an early post (February 15) on ThinkingAnglicans responding to the "anti-speech, anti-assembly" Nigerian legislation.
The post includes a link to the respones of Changing Attitude Nigera, a gay and lesbian Anglican group in Nigeria, as well a couple of interesting articles in the Nigerian press. The comments to the post are interesting, as well.
My suspicion is that it is because of groups like Changing Attitude Nigeria that the Archbishop Akinola has lent his "prestige and resources" to the legislation. These groups have foreign support and are therefore considered to be outsiders -- it is because of Changing Attitude that words like "colonialism" are thrown about. I think it is because of Mobil Oil that the word "colonialism" should be used, but that's just me.
BTW, there is another press release from Changing Attitude Nigeria that is worth the read, written in response to a letter by the Rt. Rev. David Onuoha on the Church of Nigeria web site.
