That place sounds more like a place of Avodah Zara. They say they come to daven to Hashem, but they clearly have no intention of serving Hashem. Rather they serve themselves and have Hashem as their excuse. It’s like ovdei A”Z who create their own deity to tell them what they want to hear and do.
With such an arrogant response of “get … out of my shul”, it seems that the ringleader is calling the shots and the rabbi is a puppet.
