The subjectivity of morality and the moral majority? How do we come to terms with 6 billion empirical perspectives?

You know, it bugs me when people of like mind sit around and talk about like things in a mutually gratuitous rallying session. For that reason I will see how long I can go without revealing too much of my leftness or rightness (since those unfortunate polarizing labels are so hard to avoid). I would love to somehow have the opportunity to get a discussion going with people from as far left, right and middle (how far is middle?) on any practical, political or spiritual subject to bridge the gap that is instantly created with these labels. There's a quote I heard once that I like: "a conservative is a liberal who has been mugged." conversely, how about "a liberal is a conservative that got laid off one month before their retirement would have kicked in"? We are all people concerned with keeping the bills paid, a roof over our heads, food on the table and that our children get every opportunity they can to have a good life. Black, white, Jewish, Muslim, Christian, Buddhist or pagan we can mostly agree on those fundamentals, can't we? What else can we agree on? I'd love to hear comments on that subject: what are the universal truths or values amongst us?
