There is a line, we all make one, we all want some form of definitive we can indentify with and get comfy close to even if that blanket can never cover the feet and toes. So stop the fucking hedging and put something in here of substance.
I don't think we entirely disagree, Shane. As you say, each of us has a line about this or that subject. the patriotism thing, sexuality, income, class, etc.
Society's lines are the summation of all categories of boundaries which we impose on ourselves and inflict on others.
Thus, the boundaries that society produces, perhaps more accurately described as taboos or morals, are not thin, sharp lines. They are broad, convoluted and fuzzy. The more free the society, the fuzzier and more convoluted the boundaries. I think this lack of social clarity is what makes OT such a vital place. You get people whose apporach to life are as similarly unidimensional, while diametrically oppositional, as Tahloube and Feel The Love. Both are fanatical adherents to their belief systems and neither are tolerant of the beliefs of others.
Or we have the example of yourself. For some reason people seem to think it is important to mention your sexual preference in a consistently belittling way while they think they are being humorous and broad-minded. It reveals neither, IMO. But that's just based on the way I draw my own lines & taboos.
