You're confusing the issue. The basic fact is that being humanist or not being Christian has historically not been a factor in whether genocide or other atrocities will be committed.
Further there were no plans for Indian genocide -- despite claims by American haters and the fools from public schools who believe them.
I did say indiscriminately. We didn't have a plan to do it, but we killed thousands anyway, likely millions if you count back to our original occupation of the Americas. We did have a lot of people who objected (the treaty that led to the Trail of Tears barely passed), but our Christian majority, led by the devout Christian Andrew Jackson, still passed it and ordered them sent on their death march.
You don't have to be an America-hater to realize we do have a somewhat checkered past. However, unlike Ward Churchill and Jesse Jackson, I believe we should just look at what happened and try to avoid it again, not keep whipping ourselves for it or try some centuries-late reparations.
No, I'm not. What you said was "We, as a very Christian nation, indiscriminately slaughtered Indians -- men, women and children as Hitler did to the Jews." I am pointing out, we didn't. Not even close.

If you don't want to be thought of as an America-hater, don't compare anything we ever did to what Hitler or Stalin or Mao did.

Christianity is inarguably a moderating force on the level of violence. As bad as you think the Conquistadors were, the Rome where Spain has its roots, makes them look like kindergarten teachers.
