Rules for capitalization are enunciated in grammar books of languages with lower case and capital letters. In German all nouns are capitalized. In English, aside from I and God, all proper nouns are capitalized. In the languages of India there are no lower case and upper case letter. In Arabic the form of the letter changes when it is at the beginning of a sentence.
There is no need to add another element (orthographic) to religious complaints and insecurities which are causing enough psychological havoc already.
Peace!
