Actually, this is news to me. I was not aware of any in-fighting amongst the Orthodox.
I knew there was some infighting over the last handful of years:
EP vs. MP over Estonian parishes.

MP vs. EP over leadership

Old Calendarists vs. EVERYBODY

Greeks against...the whole world? (not quite)

Within these Churches there was a brief but bitter schism in the Bulgarian OC, a ridiculous four way nightmare schism in Ukraine, problems in Jerusalem, etc.
Nobody is perfect. We have our problems too.
