This is such a silly conversation. How do you know she’s not Jewish? Maybe her mother is Jewish and her father isn’t. Maybe her mother converted. Maybe her grandmother converted. Maybe both her parents are Jewish from birth and she just looks Asian. Maybe anything.
So someone saw somebody who he guesses is a convert based on her facial features, and is SURE she wasn’t covering her hair (because he got a really good look at her head, and knows this for a fact) and is discussing her status as a Jewess. Shame on everyone here. You have no idea, and to cast aspersions egregious.
For shame.
