Actually just the other day a non-jew asked me if there is different kind of judiasms, and I told her no, that there is just one- that we follow from the Torah.
She asked me why some people are “jews” but virtually assimilated. So I told her that being a jew is a born status. Some people choose to observe the religion, while others don’t.
I did not, however, mention about reform, conservative etc cuz I had no idea what to answer her on that
