gavra, you are free of course to decline to respond to Doc or my own points, which is precisely my point: Don’t insist others must respond. I’ll assume you have come to the realization that the Rishonim are correct, and you are mistaken, not the Rishonim.
As far as this ring discussion, a Jew should not be flirting with others in the office, Gentile or Jew, regardless of his marital status, but kal vchomer if he is married. If someone feels the need for a shmira for himself, let him wear a nametag on his jacket or shirt pocket that states “I am married.” Unusual? Sticks out? Certainly less so than a Jewish man wearing a ring.
