Yates,
Besides media outlets, it's these groups ( Both Black, White, & Others) pushing for that cultural backlash as well. It's one thing to be involved in a cultural group for whichever yours interest than an entirely different being involved in a Supremacists ( Any ideology/philosophy similar) group. We can learn from each other without antagonist behavior.
When you mentioned the table scenario I have seen it throughout my life as well. I think it some mutual interest to it. Some white guys talk about fishing, hunting, & tailgating which some Blacks can relate and add to the conversation. Others are just plain lost in that talk and just talk sports, sneakers, rap industry and etc.
