Don't forget to add in the mentally handicapped, homosexuals and gypsys. I think that the total number of jews killed by Germany is robably aroudn 6 million. Whether this is the exact number or not shouldn't matter though. The fact that these people where slaughtered because of their race is tragedy enough in and of itself. It is frustrating to me though, that often times the jewish tragedy hugely overshadows the deaths of all of those already mentioned during the war. The number of Russians slaughtered was probably at least 4 times that of the jewish holocaust, and yet many people outside of Russia never remember it.
As for the comparisons to the conqering of the native americans by europeans, I think the only similarity is in the total disregard for human life exemplified in both instances. Besides that, there are more differences than similarities, and I agree that there is no reason for modern day Americans to feel responsible or to take blame for those acts so long ago. I am only responsible for my own actions, or inactions, not for anyone elses, and so are all of you.
