Get a grip! Infanticide of female babies was so common in the old days because females did not contribute to the hard work as the males- lots of poor ignorant families KILLED the girl babies AFTER they were born because they were just another mouth to feed. That did not stop the rest of the world from progressing, or stopped goodness in the heart of men from evolving (Jesus asked us to love our enemies, and all I can see from the comments of the so called Christians is HOSTILITY). Fanatic Muslims can fill each others with so much hate to the extent that people kill themselves in order that they may kill others who they hate so much. Fanatic Christians who are so obsessed with the abortion issue can get very close to resemble the BARBARIC JIHADISTS.
This kind of stuff was happening in this country - last actual cases I know about were in 1983... Euthanasia occurs everywhere, not just back in Nazi Germany.
They weren't the first, or the last, to do it. They just did it in ungodly numbers.
It appears you're getting too wound up (for me) to have a conversation with about this subject...
Take care
