I'm in CO and FF has taken off amongst women. At first I noticed all female FF clubs on stream. Now there are many female FFers alone or more often in pairs. Really great to see. They are now working in the fly shops, have real expertise, and are comfortable sharing it.
Back when I was teaching FFing I really enjoyed teaching the women. I was involved in, or ran my own, "Women's FF Camps". They were separate from men's camps because the social space was different. The male camps were more aggressively success oriented, and there was often a competitive thread going on. Everyone wasn't like that, but that energy always found its way in to the mix. Also, in the male camps, there was always damage to cabins and some stealing.
The female camps were blissful by comparison. One thing I noticed, and appreciated, was that the women were more outwardly thoughtful and appreciative of the aesthetic of being in nature, on a river, and tying and casting a fly. Or, at least that theme was more prominant.
Reminds me of the debates about getting more females into science, back then. Girls were taking a back seat to the boys in mixed groups, not stepping up to leadership or ownership space.
Cultures change and although I'm not directly involved anymore, it appears the women are finding their way into participatory and leadership positions in many fields. In fact, some statistics on navigating the academic and professional worlds, esp in periods of great structural change, are showing that women are actually more successful at navigating change than men. My experiences in introducing FF to women has me not surprised in the current trends in the least.
As far as LGBT goes, the groups of people that don't fit the biological norms were always a fearful and therefore silent minority. I guess my take follows Doc Watson's comment, "I don't care if you have green skin and wear a bone in your nose; If you can fiddle, you're OK by me."
