they are digging their own grave... saying that the Faith is all nonsense... is similar in some ways to pornography.

Question: You mentioned that certain individuals have set up Internet sites being opposed to the Faith, and you mentioned that by doing that they are digging their own grave. Aren’t they helping other individuals to dig their own graves too even though some of them are not Covenant-breakers?

Peter Khan: They could help extinguish ones faith even though they are not Covenant-breakers. They are not violating the Covenant. They are saying in various forms the Faith is all nonsense. It’s not a violation of the Covenant, where you accept Bahá'u'lláh but not His provisions for authority. But, it can be spiritually corrosive. It’s similar in some ways to pornography. I mean what do you do about pornography? There are various Internet filters. You basically depend on bringing up your kids so that they have the degree of internal restraint, so they won’t get wrapped up in pornographic sites. So it is in developing the self-restraint not to get involved in spiritually corrosive materials on the Internet.
