I'm not sure if what I can share with you will be useful or not but, here goes.
When I went to Bethel from our hispanic congregation in Texas in the late 1960s, I was shocked at the coldness of the "brothers" in Bethel. It was one of the reasons I was sure I had made a mistake within my first 2 weeks of Bethel service.
As I spent more time there, the overwhelming impression I got was that if you were not "German" enough, you were nothing. Note that my understanding is that Knorr and many of the good ol boys were of German extraction. I could be wrong but that is what I was always told. Everything there seemed to be sort of on a German model, from the way the schedules and assignments were set up to the food.
I've got no problem with Gemans. But the culture strikes a Latino as being a little cold. I have a student in Cuba who is a diplomat and went to Germany for a while and that is his impression too.
In Texas, everyone was friendly in our cong. There were fights and the inevitable gossip (Think the gringos are bad about gossip? They are no contest!) Despite all of the problems, the atmosphere was warm. In the English cong. that my parents attended there was a lot of gossip too. But the most outstanding thing was the hierarchy. If you weren't the right sort of folks, the hicks brothers would not have much to do with you.
I have never attended and will never attend any kh here but, in general, the latinos are slower to shun someone. It is just considered bad form here to ignore someone you know or who is connected to someone they know.
To be fair, in the US I met many very nice people who were witnesses and had a lot of friends. It is just that the culture is different. We generally describe it as being colder.
For what it's worth. These are only my impressions. As far as the "German" comments, perhaps some other ex-bethelite could give his or her impressions. Did you hear the same comments in Bethel?
