No one disputes that the 20thC saw an unprecedented level of killing in absolute numbers.Your efforts into trying to skew a known and factual answer into one that fits your beliefs is fail. I don't know why anyone disputes that the 20th century brought unprecedented levels of death as well as other ills.
The info should be pretty easy for you guys to find.
Who believes that what I'm saying is not fact, and who's debating me on this because I'm a theist and therefore they must oppose?
However, the world was far more deadly prior to the 20thC.
