I'll copy and paste what I posted in the forums about this...
Unfortunately like a lot of people I treated today as a holiday where I had a day off work. I didn't realize it was MLK Jr. day until recently, probably like I do each year.
Even though this holiday has no significant cultural significance to me, it did remind me of something. I was watching one of the old Star Trek movies today and Nichelle Nichols came on screen. I remember a story where Nichelle was close to leaving Star Trek, but MLK was a huge fan of her part in Star Trek and asked her to keep at it, which kept her on the show.
I read more about the impact her part caused. MLK inspired a lot of people and in a way he impacted my life, so I thank him for all he did.
So I celebrated this day by watching a show he liked, with an actress who showed equality on TV.
