Have you heard of the Japanese Schindler?
http://www.pbs.org/wgbh/sugihara/film/index.html"As Japan's consul to Lithuania, Sugihara risked career, disgrace, his life, and the lives of his family defying Tokyo by writing transit visas for refugees desperate to escape persecution. In August 1940, Sugihara spent upwards of sixteen hours a day issuing visas, until Soviet-occupied Lithuania forced the final shutdown of the country's last remaining consulates. In the end, more than 2,000 Sugihara-stamped passports allowed hundreds of families to flee Europe through Russia to safe havens abroad. Today it is estimated that more than 40,000 people owe their very existence to Sugihara's heroic acts of humanitarianism."
Maybe you can use part of the pbs film in a presentation.
Your liberal professor surely can not take offense to this topic.
Although I also like pkmb70's suggestion about anti-Semitic vandalism.
