Anyone here who read the fanfic, "The boy who Yid"?

I’m reading The boy who yid and there are a few things I’m confused about and I’d love to get other people’s opinions. For those who haven’t read it, it’s about an Orthododox Jewish boy who goes to Hogwarts. I highly recommend it. https://www.fanfiction.net/s/10847788/1/Goldstein
