There is much debate over gay rights within the Anglican (Episcopal) Church which is rooted in both the west and countries like Nigeria.
The west has been moving toward acceptance of sexual diversity while much more conservative attitudes prevail in African branches of the church. Acceptance of sexual diversity includes GLBT people while more conservative thinking sees a stronger link between sexuality and procreation. I think the world needs more sexual diversity as over population indicates that there's more than enough procreation.
I would not want the rest of the world to follow Nigeria's leadership. Could be the international Anglican Church needs to split as the theologies are in different worlds. I'm not part of that church, so I'm no expert on their politics, tho. I think it's already split here in USA.
A lot of our world's outmoded ideas, like conservative attitudes sexual diversity, can lead to problems. If procreation is the only accepted outlet for sexuality, it can cause overpopulation problems. This becomes an environmental issue as people, all over the world, aspire to a richer life.
From what I read, Nigeria's population is growing rapidly and may surpass the US in population within a few decades, tho it has far less land area than the US. An environmental nightmare as traffic and consumption rises. The average American's consumption of natural resources is higher than that of the average Nigerian, today, but people all over the world aspire toward more consumptive lifestyles. Think of all the get rich quick schemes, on the internet, that originate in Nigeria. Of course that proliferation of scams doesn't necessarily represent all of Nigeria, but it's hard for me not to bring it up.
The situation of people's aspiration toward growth in consumption prevails around the world. China is an example of vast populations aspiring to live richer lives. For instance trading in bicycles for cars in recent decades. China is often held up as an example of why people wouldn't ride bikes, in mass, if they don't have to. It's used as an example for why Americans aren't likely to cut back significantly on automobile use.
For our world to remain livable, there needs to be more innovation and acceptance of diversity in both sexual lifestyles as well as traditional aspirations for what a richer life entails. There is some good news from China, however. Bikes are making a comeback. Not only are crowding and pollution pushing some Chinese into bicycling, but new technology is leading the way. Uber / Smartphone technology is making a new bike sharing program very convenient. See How the smartphone brought young Chinese back to bicycling.
We need forward looking innovation, not backward looking mindset, as this crowded, aspiring world evolves. We need innovation, especially in the face of climate change.
