Ok, you could have made that more clear, I didn't even consider the possibility that you didn't know the Jews did bad things when you heard that, so it sounded to me like you just wanted them to say bad things about Jews in this lecture rather than you feeling deceived.

I grew up in Sweden in the 90s and the debate was raging already then here due to significant Muslim immigration, so there was always people who brought up all these bad things the Jews did there, so I couldn't imagine an adult who cared about the topic not knowing.
