"Religions are kept alive by heresies, which are really sudden explosions of faith. Dead religions do not produce them." Gerald Brenan (1894-1987) British writer
On the other hand, to the extent that a SPECIFIC religion is associated with national identity, and exists as an "established" church, then perhaps it's true that the appearance of new sects is a "threat." If Russian Orthodox Christians leave the church and embrace American-style Pentecostalism (a Protestant sect), then to some Russians this must be proof that religion is "decaying" in the Russian soul -- and a "net loss" for Russian identity.
Whereas Brenan would take the conversion to a non-Orthodox variety of Christianity as proof that some Russians continue to be intensely interested in religion, and in having a relationship with God/Jesus.
PS. Regarding the German children who fainted during sex-ed class -- perhaps you're right. It's difficult to be sure because neither of us actually knows what the pictures looked like, and whether they were truly of a pornographic character. But, incidentally, the first name of the father was given Оймен as in the story. And after thinking about it, I realized that this is actually the Cyrillic form of Öğmen-- a Turkish name. To me, this puts a different spin on the story; there was a "cultural clash" between the German school administrators and a non-German immigrant family.
