It seems to me you're getting confused by mixing "Christianity" with "Christians". What he complains about is not "Christians today taking the moral high ground", it is Christians today claiming that Christianity as a religion is morally better than Islam as a religion, in some kind of ahistorical, contextless moral ranking of religions.

Regardless, my point was not to somehow blame Jeo for identifying with people who lived long ago, far away or both. Essentially everybody in the world does that, it's entirely natural. I was merely profiting from the occasion to illustrate Ghavrel's point about how people's actions do not occur in a vacuum, and have contexts, as we all have our personal connections, associations and emotions linking us to other people past or present. Which does not mean that people don't bear responsibility for their actions; but it does mean that actions can lead to reactions, sometimes even from people quite far away or quite a lot later.
