The OP states....
social stigmas persist in interracial marriages as if that isn't good. To me, the question should be...Why are there stigmas in the first place? Should they be overthrown? What are God's teaching on what some regard as "social stigmas?"
Is it now okay for same sex marriage because someone is gay? What does God say?
Is it now okay for interracial marriage because someone thinks so? What does God say?
Is it now okay for people to take handouts from the government rather than work? What does God say?
Is it now okay to allow the few to rule the many...to allow atheist to tell believers you can't pray, you can't refer to God, you can't, you can't, you can't because it may offend someone? What would God say?
Is it now okay to do whatever anyone wants because...they think it's just fine and dandy?
Stigmas are defined as, "
a mark of disgrace or infamy; a stain or reproach, as on one's reputation." So, should "stigma" be used in regards to Biblical teaching on how one should live one's life? What would God say?
