'Christians and the unbelievers...'

[HnauHnakrapunt]

Just listening again to David Bowie's 'Loving the Alien', and although the song is mocking the standard nomenclature (just call them aliens), this phrase struck me a bit. Namely that some people assume in their language there is no belief or faith outside Christianity, or denial only, which I can prove otherwise in five minutes.
Ah, yes, there are the 'infidels' too... but at least some of those were faithful enough to their own beliefs.

And of course Bowie himself (Christian-Buddhist-Satanist-Spiritualist) married a Muslim woman. As far as I know, neither of them tried converting the other side.
