If ROCOR was not canonical, and did not preach the Truth, and all Her members were just as some of you say, then the Moscow Patriarchate and others wouldn't be putting so much effort and hard work to exterminate Her and bring us all under its control.
Andrew I understand your confusion, you are not alone. Many persons both from World Orthodoxy, and from other religions are also confused. There are the many denominations claiming to the the One Holy Catholic and Apostolic Church, calling themselves Church of Christ, Orthodox Church, Restored, Renewed, etc. In addition to this, the names put on our Church by Her enemies, such as the ones you mentioned. For example, the term "zarist" was used by the soviets, who were instilling in people the classical monarchphobia, and by applying that term to the Russian True-Orthodox Church, they tried to scare people away from us. We take pride of being the continuation of the pre-revolutionary Church, and our fidely to the Zar, and we use this term with pride, but it is not our official name.
One day when I was listening to a sermon in an oriental orthodox church in India, the priest in his sermon refered to his church, not as malankara, but as the One Catholic Church. They insist that we left the Church and accepted the "innovations" of Chalcedon, and modernity. I, as a christian, can see the truth, but the unenlightened, like you, can be easily confused and deceived.
My piece of advice, repent, and sincerely seek God, and He will surely enlighten you and then, you will see. This is goes to all of you.
