What I am still struggling with is what, exactly, is a Christian value.
I don't think prohibitions against murder, other violent crimes or theft, for example, are helpfully labelled "Christian values" - even if they have not been entirely universal throughout the history of civilization, they are extremely widespread (and were before Christianity, too).
If, for the sake of argument, we accept that Christianity is the root cause (or at least a major one) in the now widespread (in the West) belief in universal human rights, I still find it hard to consider "equality" a Christian value when you consider that, for much of their histories various Christian churches upheld and advanced racism, sexism, religious intolerance and homophobia (and some of these still remain present, to differing extents, in churches).
I'm persuaded that Christian theology almost certainly had a very significant role in popularizing ideas that were an improvement on what came before it in Europe, and ultimately put the continent on a path (or moved it more quickly down a path) that led to modern notions of universal rights and eqaulity, which may not have otherwise occurred, but the concept of "Christian values" remains pretty illusive, to me.
