Watch this. Here is just one quote from the video:
“[Dr. Martin Luther King Jr] said ‘I am the biggest Trekkie on the planet’ … He went on to say how important Star Trek was, that images on television permeate the culture, either for the good or for the bad, and this is for the highest good. He said you cannot abdicate your position. You are changing the minds of people across the world, because for the first time through you we see ourselves – what can be – what we are fighting for… ” Nichelle Nichols .
