It's inappropriate to belittle others' religious beliefs.
Troy is at work when his Iranian coworker Lola tells him that her religion iis Zoroastrianism.
Troy wants to react with surprise.
Troy tells Lola that he's shocked because he's never heard of that religion before and wants to know more.
Troy laughs and says he's never heard of Zoroastrianism and that it sounds made up and stupid.
Lola is delighted that Troy wants to learn more about her faith and is eager to tell him all about it.
Lola is annoyed that Troy thinks her religion is fake and is disgusted that he's laughing at it so immaturely.
