I hate to tell you this, but there are sinners in the ROCOR and Old Calendar churches as well. I bet any priests of those churches would tell you that you could very well run into these problems at any parish, unfortunately.
Yes, we are all sinners.
However, when I encountered a similar situation in an OCA church, we left that parish as did many other folks. Finally, the Bishop noticed the revenues were drastically down and took action against several nasty parishioners. I am very delighted to be in an Old Calendar parish now where people truly do love one another. Sometimes changing parishes is in your best interest
To the OP: I will pray for you.
Lord have mercy. Lord have mercy. Lord have mercy.
