JoeMo, There is an ignore feature in a drop down menu which allows you to block certain individuals. You can access the feature by clicking your name in the upper right corner of the webpage being displayed. In the real world, we can just walk away from people we find obnoxious. Here, we can "block/ignore" them.
The problem of race is a complicated one. Strangely, some of the most racist rhetoric I have ever heard in the States came from "religious" people. One was a young Black Muslim. The other an SDA pastor in Vallejo, CA, from the pulpit during "prayer" meeting. Racist hatred was abundant at Fuller Seminary in the 90s. The racist sentiments posted on the public bulletin board were shocking. It doesn't even take a generation for some SDA African immigrants to identify with racist ideology in America. It's really a sad thing to have Christian friendships damaged by racist influences. It's not only race. Mexicans, for example, are divided into geographic groups such as the Nortenos and Surenos. Blacks are divided into Crips and Bloods. California prisons have accepted that racial integration is an impossibility. Inmates are segregated by race which is usually connected to gang affiliation. In prisons where segregation is not practiced, it can lead to cross race sexual exploitation of the physically weaker inmate, violence, probably murder.
Anyway, try the ignore feature to enhance your online experience.
