I don't think that a lot of people on this forum has energy to do that. This is more of a social theme (in a forum full of exact science worshipers) and "converging people to another faith" is very hard work often unsatisfying. Some here have methods that do just that and are: less time and effort consuming, more direct and proven effective. KMDave has the best approach IMHO. He often helps you to help yourself and the process alone will select the believers (who will dig down) from nonbelievers (who will think it's too much hassle).
