European/Global Christianity Versus American 'Christianity'
I'll admit, I'm an atheist, but NOT because I despise Christianity (on the contrary), but because I simply don't believe, for rationalist reasons. That said, I do suspect there's more to the universe/cosmos, and possibly spirituality than any of us, including the scientific community, can possily comprehend.
Still, whilst I find it impossible to believe, just as I suspect it's impossible for any *genuine* theist to *stop* believing, and thus don't begrudge either theists or more fellow atheists/agnostics, I actually have a lot of time for *genuine* people of faith.
Even setting aside the signficance of Christian Socialism, the importance of Methodism to abolishing slavery and the Labour/Union movement, Liberation Theology in many South American Catholic nations, and the apparent movement of Pope Francis towards a more progressive and out-reaching form of Catholism (which is certainly not to say that the Catholic Church doesn't still have many issues), I've observed that in the UK many of my fellow volunteers and leftist activists, are themselves devout Christians and Muslims, among other religions. The volunteer organisation for the homeless I regularly help at is predominantly made-up of Christians, Muslims and Hindu volunteers (although there are a few atheists and secularists, besides myself), and a lot of them lean to the left (often far more than I do; which, when it comes to issues like Israel, isn't *always* a good thing; most of the leftists I know, aren't anti-Semitic, but a few, otherwise well-meaning ones, have occasionally shown some dubious, albeit low-level, prejudice towards Jewish people; and just to be clear, some of my fellow volunteers are also Jewish, but they tend to lean more on the secular/atheist side).
Anyway, the point I'm making is that I find it very odd how dominant the right seems to be within US Christian circles, and vice-versa, even though I find little in common between the free-market, pro-capitalist, anti-immigrant, anti-tolerance, benefit-slashing, top-tax-rate-cutting, white supremacist attitudes of right-wingers, especially Reaganite/monetarist/socioeconomic conservatives (i.e. the tax-cutting/benefit slashing 'classical liberal'/trad Republican ones), and the more populist anti-immigrant/white supremacist brand, that had dominated the party post-Obama/from the Tea Party eras up until Trump (although admittedly, the two brands often seem to merge, more for convenience than out of shared and consistent ideology; many 1980s-era monetarists, of your Alex P. Keating type, would abhor the viscerally racist/misogynist diirection the GOP has taken in recent years).
