The Catholic nun would like to talk to you about Jesus Christ, and invite you to become Catholic.
Hijab Lady's husband would like to cut your head off if you don't grovel before "allah" and babble about "mahomet" being a prophet.
You and Mrs. Busek are very observant and astute.
Western civilization is infused with Christianity / Christian values and norms. For that reason, even non-believers (as long as they were acculturated in the West) will not find friendly interactions with Christian clericals abrasive or offensive.
