Warning: political activism ahead!
Yesterday was the summer conference for us LGBT lefties. Now, most of what went on doesn't really belong here, but what really struck me was that after a couple of years of the Bisexual Democrats project, it has started to take a more serious hold, with both the immediate recognition of the pink, purple and blue stuff, and requests from new members of where they could get teeshirts, badges, or where to download logos to use on their own work.
I suspect the number of out-bis is a mixture of the targeted recruitment and of a wider visibility thing. But having the bi materials produced is helping to reveal the 'hidden bis' - I look forward to citing it as good practice!
