I am not Russian so I do not know all the political intricacies and views of its people, nor am I yet truly Orthodox as I have not been able to begin the catechumen period due to living a great distance from any Orthodox church. So please, do not address me with such arrogance and disdain as if I should know better. Make your case in honest discussion and we may have a meaningful dialogue.
From what I have seen Putin is very much a defender of the Church. The west, meaning its governments, secular philosophy and academia and much of its population, is an enemy of Christianity. The west is a godless and secular land, even its Christians living lives cut off from anything sacred. I do not know the exact moral state of Russia but from what i can tell the Church still has authority and honor and its people still live by traditional principles (family, anti-sodomy, etc). As for Roman Catholics many, many people both Orthodox and not see them as an enemy. While you may disagree with this view I do not see how it is a sin for Putin to be anti-RC.
Now tell me how Nationalism is a sin. I am a staunch Nationalist for Scriptural and logical reasons. I believe globalism, not nationalism, is a sin and tool of the Devil.
