What is real in this...What is real in this: Extermination of the Jews in Germany, "Holocaust." "!!!" Or Extermination of the Palestinians in Gaza.
The Palestinians in Gaza may well be being abused, but their plight is in no way equal to that of the Jews in the Holocaust. In the Holocaust, millions of Jews were purposely killed. In Gaza, Israel has killed Palestinians, but not systematically. It does blockade them and make their lives miserable, but that is nothing near to being the same as killing them.
People have been killing people since there've been people. This is a hard, sad fact of history -- Armenians under Turks during World War 1, Ukrainians under Stalin and Koreans under Japanese in in World War 2, "ethnic" cleansing in our current day. The point is not to assign blame, but to minimize such occurrences.
I, too, must agree that the Holocaust far exceeds the devastation and severity of the Palestinians in Gaza. As enotechris points out, people (large numbers of people) have been murdered from the beginning of time. But, regardless of the numbers, the more important part is the impact on humanity.
