What are some differences that you noticed between black/white/spanish congregations? Have you noticed any racism/discrimination? Did witness talk negatively about other races? Growing up, most looked down on the spanish congregations (in the late 80's) but there was never any blatant discrimination. What has been your experience?
Did friend in your congregation not like /talk about other races negatively?
For as much as the JWs want to be and portray themselves as not part of the planet, and for as much as they claim that they have some "spiritual paradise" thing going on, the reality is that they aren't any different than the rest of the world. Socially, congregations behave according to the local culture. It's impossible to expect all congregations to have the exact same social characteristics.
As for racism, just like the rest of the country, I saw it everywhere in all the congregations I went to.
In one of my arguments with my father, he told me that the JWs don't discriminate. I laughed and said: "Sure, they don't discriminate; they just claim to be the one and only group that has the one and only truth, and the only ones deserving to live. Nothing, just that".
