All Jewish people have had this type of argument at some point:
Person 1: “Did you know (insert name) is Jewish?”
Person 2: “No, he/she isn’t.”
Person 1: “Yes, he/she is! My mom told me so!”
Person 2: stabs Person 1 in the eye with a rusty fork.

We here at Jmerica are no different, but we have learned over the years (after considerable opthamology bills) that a quick Google search settles things better than a rusty fork.
