Regarding Mel Gibson's upcoming Holocaust series

The real statement made by Gibson regarding the Holocaust was that there were a lot more groups that died in the millions in recent history. The quote:

"I have friends and parents of friends who have numbers on their arms. The guy who taught me Spanish was a Holocaust survivor. He worked in a concentration camp in France. Yes, of course. Atrocities happened. War is horrible. The Second World War killed tens of millions of people. Some of them were Jews in concentration camps. Many people lost their lives. In the Ukraine, several million starved to death between 1932 and 1933. During the last century, 20 million people died in the Soviet Union."

Fair enough. I've known people myself who were irked by the fact that there is so much attention paid to the Holocaust, yet very little is commonly known about the millions dead under Stalin. But if this is truly Gibson's attitude, then why doesn't he make a high-profile miniseries about the Stalinist purges or those that starved in the Ukraine. Instead he's making yet another film about the Holocaust. Very odd.
