I'm not sure what that has to do with the piece you responded to, but it sounds more of a social, psycological, issue, than an actual theistic one.
Theistic discourse does not happen in a vacuum, but is embedded in social, psychological and possibly other issues, which affect the theistic discourse.
Even if it takes place on a highly academic level.
One having to justify their belief to some group of people claiming to be the standard of what it is to be human, sounds like a communist type of approach to society. In this, you are deemed deleuded if you cannot produce God to the board of directors. Once you are deemed as such your value as a human being diminishes. Dangerous stuff.
And yet it is fairly common, theistic communities being anything but exempt from that.
Why shoild you expect testimonies to be the same?
''A theist'' is ''A person''.
Every single person is different.
To judge ''theism'' on the testimony of ''some'' people, is NOT what ''theism'' is about.
To a person who is not a theist and/or who is not a member of a theistic society, things look strikingly different, though.
They have an acute sense of being an outsider, of not belonging, and those who are members therefore appear the same in some crucial way.
Members tend to enforce this impression - "We are in, and you are out."
Doctrine often enough enforces this too - "Nobody gets to God except through this religious/spiritual organization."
An outsider cannot meaningfully distinguish between the grades of devotees and such.
This is how to an outsider, being hurt by one member is like being hurt by all/any members; if one member claims something, it is like they all do.
And when members appear to disagree or differ, this creates insurmountable-seeming confusion for the outsider.
I think one has to somehow come to a rather advanced level in order to become individualistic and to see members of a group as individuals, but such individualism does not seem to be the default for most people.
If that is so, then many atheists are irrational, which flies in the face of
their claim to righteosness.
Atheists have to save face too.
