white christians need to begin recognizing the common sense reality that they are white, that this is unique, why it is a unique expression of gods will and that the races exist for reasons to be respected not to be frivolously dealt with for economic reasons capitalist or communist nor prideful virtue signal-style compassion and tolerance parades that get the daughters raped and killed. 

they can then ally with the other whites not of christian persuasion for political and geopolitical purposes but thinking that there is gonna be a mass reversion to what exactly? Norse? Greek? combo?

seems less reasonable than acknowledging there are a billion christians and they arent going anywhere... you will need them to provide numnerical defense against elements of islam, for instance, that are corrosive to european peoples general interests and preferences.
