I think you'll find that this video is worth your time.
That said, it's probably not the video to send to your dear Aunt Frieda who's never seen a gay person, much less studied up on LGBT history. It's more pep rally than substance; more inspiration than introduction. The story isn't told in chronological order and it leaves out some pretty important stuff (I watched it three times and didn't see anything about the Stonewall riots, for example).
Still, it is full of stirring images. In fact, I hate to admit it, but cynical and jaded as I am, I did feel a definite shiver once or twice.
Oh! And is that Vandy Beth Glenn behind Barney Frank? I do believe it is!
Hat tip to Good.Is. And hell, a hat tip to us, too.
