Embarrassing in Noahide Law
From Wikinoah English
Rabbi Yoel Schwartz (Jerusalem Court for Bnei Noah)
A person is not allowed to insult or injure the reputation of another person in public. It is better that he be thrown into a burning fire rather than to embarrass someone else. An example is Tamar who avoided publicly shaming Judah even though she had been sentenced to be burnt. Tamar was a child of Noah.[1]
