Charity,
You have wasted a lot of disk space showing off your propagandized mind. As Marius pointed out, "Mother Russia" is what you might rightly refer to as a common ethnic expression. "Holy Russia" or "Holy Mother Russia" might have referred to "White" or "Bright" originally, but after the Fall of Constantinople took on religious connotations with the idea of Moscow as the Third Rome.
So no, it is not an innocent pro-Russian phrase, but one that has been explicitly formed to deny the orthodoxy of Rome and the supremacy of the Roman Pontiff. A Catholic has no business using the language of Russian Orthodox schismatics. If you are ignorant of this fact, I encourage you to educate yourself and retract, but otherwise it shows how badly you are attempting to deceive others by pretending at its innocence.
