I was taken aside at my synagogue and told to tell no one that I was a convert. If someone asked if I was a convert, I was to turn my back on them and to ignore them.
It is considered rude to ask. Rude to discuss it. Converts are Jews. Period.
Yes, there is a bias, but most Jews don’t have the prejudice. Converts are protected from the ignorant few.
Ruth was considered a Jew before she married a Jew. (Or she would’ve not been allowed to marry a Jew in the first place.) Her children and grandchildren were considered full-Jews.
If they weren’t, we wouldn’t have had King David. He never have been allowed to become king if people considered his bloodline tainted.
I am not sure I agree with this statement. Naomi's family left Bethlehem and moved to Moab to escape the famine. Her son took Ruth, a Moabite, as his wife. Then her husband died. And according to the Law of Moses, some male relative is supposed to take her as his wife and support her.
It is also debatable that Naomi tried to talk her into staying in Moab so that she would not be "burdened" with a foreigner daughter-in-law. Boaz also goes so far to call her "Ruth the Moabitess".
Regardless, her children were considered Israelites or specifically, descendants of Judah. It is an interesting conversation, none the less.
That sounds like the story of Phineas, as in, "Phineas priest" (q.v.); they take their name from him.
