Gather your teenage children around because I am going to share a story. Not just any old story but rather a story about a religion of peace that murdered another religion of peace. Or at the very least, a story about one religious system killing those of another religious system.
"On the eve of World War I, there were two million Armenians in the declining Ottoman Empire. By 1922, there were fewer than 400,000. The others — some 1.5 million — were killed in what historians consider a genocide." Source: http://www.nytimes.com/ref/timestopics/topics_armeniangenocide.html
How many teenage children are taught about this episode in recent history prior to Germany's murder of millions of people all over Europe?
