Charity diversity

During the time I've worked in the voluntary sector it's struck me how it 90% of staff seem to be female 20-somethings. In my last job there were just two men on the staff! (including the CEO, now that's a surprise!). I found it quite difficult coping with the 'sameness' of the charity's culture. Is it because people lose their idealism after 29? Or is it perceived that charity jobs are 'soft' and won't offer much progression? I think it's an area that needs to be addressed - I was only a few years older than most of the others in my last job, but I found it very difficult to relate to them. Now that I'm working for an organisation that's a bit more diverse it's much easier and I'm certainly more relaxed. It's not just indiividuals that benefit from diversity (it's funny using that word as I'd associate it with encouraging women to participate!), surely charities are losing out on other people's skills and knowledge? Anyway, I've just read this:

NCH pays off fundraiser after claims of bullying

NCH has paid a former employee an undisclosed sum in an out-of-court settlement after he alleged that he was bullied and discriminated against because he was black and gay.
....
"Other NCH employees often referred to the company fundraising team as the 'Pony Club' as it was very clique-driven and mainly consisted of white, female, straight, blue-eyed blondes," he claimed.
....
However, it is understood that the charity disputes the claims made by Francis, including the allegations about the 'Pony Club'.
