You underestimate the power of the dark side. Melech Menashe was Mayid on Rav that he would lift his hems to run faster to Avoda Zara.
Many goyim will stay and gawk, it would take a special goy to walk away. Most frum men would walk away it would take a very weak frum man to stay.
IMHO, this has nothing to do with jew vs. non jew. This is a question of morality. The Amish, Mormon or even devout Catholic will turn away.
And it takes a strong jew not to look, especially if there are only three in the room: the guy, girl and the RBSO, and no one else will ever know.
