I'll try to simplify it for the slow learners.


Past tense:

Committed genocide


Present tense:

Committing genocide


What's the difference between these two things? When Hitler was systematically killing Jews, at what point was he committing genocide?   Was it while the killing was ongoing? Or was it only after the last Jew was killed by Hitler that what he was doing could be described as genocidal? Or was there some magic number beyond which his systematic and deliberate extermination of human beings became genocide, but not before?

Extra points for those who are capable of articulating an intelligent response without resorting to insulting language (a lot to ask for, I know).
