I think importance of White and Christian association with Russia should be permanently retired.
That Russia is a country with light skin and eyes (although they usually have brown hair) is a fact since 70 or 80% of the country is eastern slavic.
And obviously they are also majority orthodox christian, Some pick pocket examples does not change such reality. There are Muslims regions in Russia, but the demographic majority is self explanatory and the traditions of the state are also obvious.
Basically any historic figure of Russia that you can think of is orthodox so I think is pretty obvious they are orthodox. I am sure you can find some armenian christian in a random important position in Iran, but is absurd to deny that Iran is a country of muslim tradition, and that they are iranians ethnically.
The issue is that for the West being "white" does not mean have light skin. And being Christian does not mean to be Christian.
West does not consider Slavic (and Mediterraneans) to be really white. And neither it considers the orthodox being cristian
White is a synonym to be of Germanic origin, and be Christian for the West means be Protestant.
The mediterranean and slavic (like polish) catholics are simply inferior people, simply needed as a market and helpers. Slavic orthodox are in their view inferior and they hate them as much as they hat muslims and chinese
PD: Personally I hate this ethno nationalism of saying that people native from a country are of other country or religion.
Like, oh a random german russian invented that -> germans are great enginers
Iranian leader has a azerbaiani grandmother -> oh he is azerbaiani
A random jew create a company -> o jews are great businessman
A family with a ancestor 300 years ago are kigns in spain -> oh the king of spain is french
Russian zar had a german ancestor -> oh russians cant not rule themselves, they need german
Really, people belong to the country they are born. Not to the place of born of a random ancestor, or to a religion.
Other way of though just justify nazism and zionism.
