I think that the use of churches like this is good.
Perhaps people will come into the Church, see the persecution of the True Orthodox, and witness good people getting beaten up in the MP church, and then leave. I witnessed a fight at an ROCOR-MP church where a priest wanted to venerate a myrrh weeping icon. He was beaten up by a couple of ROCOR-MP deacons with the approval of the hierarchs and clergy who were very distracted and looking for True Orthodox among the crowd of people. The MP clergy were obviously not praying. I never went back after that incident.
I came into True Orthodoxy through World Orthodoxy, and there are others like me.
When I see the debates and hatred displayed on other websites that purport to be "Orthodox Christian," this does not strike me as giving a good witness. The Christians during the time of the Apostles showed their love. Where is the love today?
