I will admire the pollysyllabic words for a moment.Instruct me madam, what should I do? I am all ears since you seek my rectification and salvation
My Reer Yonis brother, you can still deliver a message while leaving the other party's dignity and ego in tact.
My go-to is I respect you very much and I think it would be unbecoming to offer my opinion on this subject.
If they still inquire. Tell them you find women of various groups attractive but are cultural and seek out women with more shared commonalities. If they ask:
Research supports that people from the same ethnic, religious, educational background that hold similar core values and beliefs have the best shot in relationship/ marital success. Birds of a feather do flock together.
That isn't intended as offensive just pragmatic and logical and no one can fight you on that.
Worst case scenario, hook her up with a madow friend from a similar background (that would be receptive). In other words, off your hands.
