Your other points are disingenuous at best. The eventual abolition of slavery in England was driven directly by Christian beliefs, however much they'd evolved in the ensuing time.
The bit about the Pauline epistles is also disingenuous. You picked one quote. Mary Magdalene was one of the disciples. Women were considered to be "in the image and likeness of God." They did not attend Mass in a separate section from the men (a separation which is still done at the Western Wall).
Lastly, who cares what the linguistic root was? And your link ignores one of the primary drivers of very early Christianity: the Romans didn't care how much you suffered. It was the Roman Empire where Christianity took off first.
"Philanthropy" seems to have been much like a lot of celebrities' "charitable foundations" nowadays: "Hey, everyone: Look at what a good person I am!"
