Most contemporary so called "anti-Sergianism" is really just Donatism. Yes I know that is a term over-used in our day (often slapped on anything party-x perceives as being "intolerant" or "too rigid"), but I think in this case it is rightly used, since the same error of the Donatists is being committed - namely, an exagerated perfectionism (and one which looks primarily at others, rather than inwardly) combined with an inability to forgive (let alone overlook whenever possible).
The fact is that there is no longer a Soviet Union. There is no longer a KGB. Those Churches under the presidency of the Moscow Patriarchate, are no longer led by Bishops who are on the payroll of an anti-ecclessiastically minded secret agency (which no longer exists, as previously mentioned.)
What can be said, is that the MP is not without it's troubles. Also, that it has some Bishops who probably were in some kind of collusion with God-fighting civil authorities, more often than not because of fear and a wicked pragmatism than out of any demonstrable ideological agreement. Well, are they so involved now? Of course not.
But I guess for some, there never will be a better tommorow. There is no looking over yesterdays misdeeds, because they themselves are obviously so free of sin.
