Religions are very different. Imagine Islam vs. Buddhism for example. The GP point is a valid one: fellowship alongside a shared set of core beliefs is invaluable. The problem is not all shared beliefs have equal merit. I could be a white supremacist and find great fellowship with other white supremacists but this would be destructive in the long run, in the short term to others due to my prejudice but in the longer term to myself because those beliefs are objectively abhorrent. But not all shared belief systems are abhorrent. Instead, groups of people for centuries have found camaraderie exploring what it means to follow a certain historical figure, Jesus Christ. Looking at his teachings you can see that this will lead to vastly different outcomes than following a Joseph Smith, a Muhammad, a Richard Dawkins, etc.
