Yes, I concur. Any minority situation basically. My father (in rural small town Alberta, Canada) related to me how a person of African descent was treated in his small town, in the late 30s or so. It would be labelled rather racist today, but back then it was just something people had never seen. With any new acquaintances from India (that seems almost weekly these days), explaining I was raised with no religion just gets puzzled looks. It's incredibly rare there.
Familiarity has significant consequences, clearly. So does peer pressure (or, perhaps equivalently, peer support).
While in these forums we tend to speak of religion as a function of beliefs, sometimes to incredibly arcane levels, the everyday reality of religious practice tends to be somewhat different.
Religious congregations very much
have a real, valid, significant role as a safe haven for people to meet each other and fulfill various social and affective roles and needs that do not always have much to do with beliefs as such.
I do not personally think that this diminishes nor conflicts with more theologically-oriented aspects of practice, but I understand that time and emphasis are limited resources, and it is entirely reasonable to expect some groups to feel the need to focus on doctrine now and then.
In any case, someone who is raised expecting such an environment will of course be disoriented by the sudden realization that someone else may have lacked a comparable environment. Particularly if belief-oriented doctrine is not a big deal in that environment.
I guess that I am making the case for unashamed, openly non-theistic religious services, despite the willing of many theists and non-theists to criticize those for often vague reasons.
