Even so, it's honestly somewhat difficult for me to generalize as regards this.
Certainly, when I think of the U.S. I would have no problem making such an assertion. But when I consider the various brands of Christians outside of the U.S., it's not so clear (and I'm thinking, for this purpose, of the present day--not necessarily of Christians over the preceding two thousand years). From my personal experience, at least, Christians/Catholics/etc. in Europe, Central and South America, and in the parts of Asia and the Middle East I've experienced, do not seem all that distinguishable in behaviors and attitudes (in this respect) from non-Christians.
And all I can say to the other part is that I have a very decided distaste for positivistic thinkers. Heh.
