Nother point of view. WyoWoman said a lot of what I was going to say about treatment of G/L in general.

But getting back to the original question: I've lived all over this country. Whatever kind of individual you might be, the more wide-open the spaces in which you live, the more likely your traits are well known. That's true for all traits, but I'll restrict it here to sexual orientation. That means that in the wide open spaces of the mid west, if you attend a folk music festival, lots of people will know about it and associate you with folk music. If you are G/L, more people generally know that in these parts of the country, too. (Kat has made that case better than I about Wyoming)

Now take the second part of this situation. I believe it would be much, much more accurate to say that Lesbians are more TOLERATED than accepted at any folk gathering. That simple change of words speaks volumes in terms of treatment of individuals. For one, means that Lesbians tend to be left alone, while Gays tend to be treated with open contempt.

Put these two situations together, (open spaces and tolerated) and it might have a lot to do with the original question.
