Interesting. What if your religion is fundamentally, wait for people to have questions and be helpful but it is a personal journey? Buddhist philosophy is not about guiding others. The doctrine was basically other people saying "How do we become as cool as you?"
Belief in the spiritual reality is fundamentally personal and if you aren't a fanatic by nature, you would never do what she is describing. Mentioning sugar, versus the danger of an oncoming car the social cost of alerting someone is waaaay more extreme. If I tell you about a car that is coming for you 10 years from now with the intensity of one several feet away is a social cost most won't bear, even if they believe it. She's funny and making a funny point but it's not a serious argument really.
