OK, well I don't claim to be an authority on this subject. It just really appears to look like two methods that reached the same result; though one sounds more unnatural than the other to us (i.e. in 2016 the US dropped 26,000+ bombs on Muslim-majority countries, but we have very few places resembling death camps, and none of them are--at least in name--racially motivated).

Anyways, both I think we can all agree are bad. I just didn't know so many non-Jews died in the holocaust.
