Yes, just like some people swear by 'everything is impure' languages, 
and go lengths to achieve immutability (e.g. Java). Why are those 
prefering purity called religious, and those using completely 'impure' 
languages practical?

Pure, partially pure, impure. All regimes can be religious or 
practical, or both.
