I think you underestimate a lot of us. Speaking for myself, I am more than capable of seeing FBBers as interesting people with full personality and not just a body.
I don't doubt that you can. But that's not the point. This board is not about general social coffee talk. It's about FMG/GTS/FBB fetishes. Sure, there's a chit-chat "Free For All" thread. But that is not a focal point of this forum.
So I'll ask again, why would a FBBer want to participate in this forum? I don't think it's at all relevant that some (maybe even most) members of this forum would treat them courteously. They can get courteous treatment at any number of places. So why participate here?
