The New Testament can be read as just literature—it’s not a grievous encroachment to give one away. What is so irritating is to realize that someone is arrogant, condescending, and would like to lead your child to Christ, and that they fully believe that their opinions about religion are the only correct ones.

but how could they think it is better than candy?
Evangelicals will stop at nothing to try to convert people.
