Reply To: Have You Ever Told Someone He/She is Jewish?

Bluhbluh: Excellent point. We don’t know for sure.

However in this case it’s kind of like Joseph’s following point

In this case, you’re very certain that the person is as Jewish as being Jewish gets and have enough evidence matrilineally to assert such.

You can def say to ask a local LOR to be sure.

Yet do you give this person who is in the dark a heads up about being Jewish?

Maybe then say to ask a LOR.

Or do you do and say nothing?
