I would teach my children you will never have to hide again. I would teach them that because I truly believe it.
That doesn't mean to not take precautions to stay safe.
I agree with the author in terms of seeing who has my back and who doesn't, but not to go as far as to say, "Did you know that that is a category of friend that every Jewish person has in their mind? Who would I run to? Who would hide me?"
I have never thought that. Maybe I should.
