I began responding to this several times yesterday before stopping myself as I felt the crucial points were eloquently addressed in the first few posts exchanged. I have a very diverse group of friends, and it is through common activities and tastes that we have remained friends since junior high school. It has not mattered that one is black/Native American/Italian, that others are Mexican, that another is Punjabi Hindu, that another is Cuban, that still another is Argentinian...
But, I too have noticed that groups like mine are exceptions to the rule.
