To my knowledge, no body on the GB is anything but a white male. (I won't get into the male only thing right now, being that it is a major issue with me.)
I have also never met a black elder, although I know of one black ministerial servant. I am not saying they don't exist, but...
I have never heard so much about my needing to be in subjection to my husband before, either. I am sure most churches do not look down upon women who leave their husbands and remarry in cases of abuse or sexual contact other than penetration (mouth contact doesn't count.) Of course, if I am to be in subjection to my husband he wants a blow-job, I don't then because it breaks the rules.
Also, do Baptists, Catholics and so on dedicate entire magazines (more than just a few) to JW's and how God is going to destroy them and their members, leaving their dead bodies in the street?
As a JW, I always got an evil happy warm fuzzy feeling when I realized those I didn't like would have their dead bodies picked by birds. So, yes, JW's are very prejudiced to the point of being very extreme.
