The "Irena Sendler vs Al Gore" chain letter
Irena Sendler was without doubt a very courageous woman who repeatedly risked her own life to save hundreds of Jewish children from the Warsaw ghetto during the German occupation of Poland in World War 2 - and there is certainly nothing wrong with commemorating her heroism.
However, what should immediately be obvious about this particular "tribute" is that it contains a lot of information about Sendler that is completely wrong. It also turns into an agenda-driven attack on Al Gore and Barack Obama, as well as questioning the credibility of the Nobel Peace Prize (early versions of the chain letter only mentioned Gore, but Obama was thrown into the mix after he became US President).
