I recently joined a women's philanthropic organization where the average age is probably 75. (My opportunities to be the youngest person in a room are dwindling, so it's nice to be the youngin' in the group.) I joined because I saw the "basic value", but also because the organization is evolving with the times. The group of 50 years ago wouldn't have been a good fit for me. The group of today is, even though there are still some aspects that feel a little antiquated to me. Those don't overshadow the rest of it. They used to be very Christian-focused, but knowing that's not how younger people tend to operate, they've moved away from that. Meetings used to start with a prayer, but now that has become an inspirational reading, which might be from a non-Christian religious book, or even entirely secular sources, for example. They also have side activities like book clubs and wine tastings. The group evolved and that is drawing in some younger (relatively speaking) members. They didn't just say, "take it or leave it, and once you are here maybe you can change it if you want", because they know that's a bad bargain few will take.
