Of the current widely accepted papabili, Peter Turkson is from Sub-Saharan Africa. He is softly pro-LGBT, and he seeks to harmonize the progressive homosexuality views with traditional African culture[0]. I don't think Robert Sarah is considered papabile, possibly owing to his message of hate for homosexuality. Overall, it's inconsistent with the recent message of the church, and it is hard to imagine that progressive Catholics would accept it.
Interesting that they identify mostly progressives as papabile. If they're right, Francis did an excellent job behind the scenes to set up the Church to do in the future what he could not in the present.
People who want to join the church prefer Latin Mass which he's opposed to.
His proclamation on blessing LGBT people caused a rift with the Church in Africa (remember why we have Anglicans as part of the Catholic Church?) threatening an area that's seeing church growth.
He's also had his mouth closed about the killings of Catholics in Africa and Asia by extremists.
The Latin ship sailed 6 decades ago... There's no going back without pissing off everyone else, assuming it's indeed true new members would prefer Latin - if you have a source about that, I'd be really interested in reading it.
This is one source I found. It's supposed to be in Pew Research but I can't use that site.
You're talking as though I'm talking about a return to Latinate Mass for everyone. It's supposed to be optional but it's being actively suppressed like some heresy.
Including it's use in Novus Ordo Missae and a bias against orthodoxy in general.
Apart from that there's the comments here against the importance of fellowship and evangelism to others actively and passively. Also a denial that being part of the church, Catholic or not (as one in Christ) is supposed to change you. What's the point of it all if it doesn't?
Here's a Reuters list for possible Francis successors: https://www.reuters.com/world/who-might-succeed-pope-francis.... Usually, Reuters does thorough due diligence before releasing something. So I'd expect their predictions are accurate.
