Are You Jewish?

I was talking to my parents about the new guy I'm dating, who happens not to be Jewish. We had been dating for several months and he even met my parents a couple times, so I thought it was completely ridiculous when my mom asked me if he knows that I'm Jewish, the implication being that if he knew, he probably wouldn't be dating me. Of course he does! Why would I date someone for MONTHS and let him meet my parents, and not tell him I'm Jewish for fear that he would dump me? Then when I had convinced my parents that he indeed knows I'm Jewish and doesn't have a problem with it, my dad tells me to be careful because in 5 years, he will be calling me a derogatory word for Jew.
