It's telling how blithely you're missing the point of what the pope(s) mean by human value. Their intended meaning is that far gone from modern consciousness, even among people who meant to champion some kind of human value themselves.
They're not talking about the economic value of humans or even the psychological value of humans as subjects with experiences and a right to liberty or care or something. The idea they're trying to recall and reinvigorate is a sense of human value that transcends that temporal, material noise altogether and that is truly universal. It's the human value that welcomed slaves, prostitutes, wretches, merchants and kings as peers in something grander than economy or state or lineage or tribe or creed.
Now, you can make a well-developed case that that's hogwash and that the human value that matters is the one that alleviates suffering or grants liberty or even the one that grants material reward for some virtue or bloodline or whatever, but that's not what these guys are talking about. They mean a human nature that is always there and always worthy, just as much when it's experiencing temporal poverty/suffering/abuse as when it's basking in temporal wealth/success/freedom.
The idea is that Christian or not, Catholic or not, it does good for everyone to think of human value that way and the critique -- for a long time now -- is that for all the flash and glimmer of technology and its material benefits, it sometimes makes it very very easy to forget.
What rot. Tell that to native Americans who were forcibly converted and enslaved. Tell that to people in the inquisition. Tell that to peoples in India and the east that were forcibly converted so that the pope could fill his coffers. Tell that to all the children murdered in Christian and catholic schools.
Christianity and Catholicism doesn’t fool me. If you’ve ever wanted to see the mythical devil - look to those preaching and they legacy of hate that they carry.
There's really no argument against the institutional and historical hypocisy. There's no shortage of people and groups that have done or currently do horrible violence against others, sometimes even in the name of these ideas.
But I don't know if that takes away from the idea itself and what fruitful counterpoint it might play in modern discourse.
So your argument is that if some people who claim allegiance to an idea do evil things, that renders all who claim such allegiance, and even the idea itself, evil? That is a pretty poor argument. It's also one that I don't think you would actually accept in another context. I bet you anything that I can find some ideal you uphold which was espoused by some vile people at some point, and I also bet that you wouldn't go "ok, I guess I have to give that ideal up now".
