I agree that while the acceptance of gay relationships has been a good thing over the past century, one thing that I think has been lost is an understanding of what I would call a "passionate friendship". People once had friendships so strong that they would risk much, even die for each other, without any romantic involvement. Then came Freud, and all of a sudden any affection between adults started to be seen as essentially sexual.
I recall on another board how one poster could not, simply could not, accept that the fact that a century ago men swam naked with each other in YMCA pools meant anything other than a wild orgy (as opposed to, say, the lack of suitable fabrics for comfortable bathing suits). They were practically snorting like Beavis and Butthead, "They were NEKKID!!!1!"
