Martin Luther King Day is approaching

Martin Luther King Day is on the 15th, and I have a bit of a dilemma. At work, the company's African American employee network is hosting a celebration on the 16th (we get the 15th off). They have asked the other affinity groups (Asian, Hispanic, women's, and GLBT) to attend the celebration and have a representative say a few words about MLK Day, what King meant to us, etc.

The chair of our GLBT group had asked for volunteers a while ago. I emailed him the other day and he said no one has stepped up to the plate yet. (In defense of our network, we are a pretty small group. But I am forced to admit that our membership is almost entirely white). We can't let MLK day pass and have our group not take part in it. So I was asked if I would say a few words.

I know there's a lot I can talk about. There are so many parallels between the struggles against racism and against homophobia (though I am also told that many racial minorities do not like their struggle being compared to gays and lesbians' fight for rights). I am just extremely nervous about doing this and not sure of what I'd say. Plus I don't have a lot of prep time.

Any ideas?
