Martin Luther King "i have a dream speech" reaction

yesterday in english class we listen/read Martin Luther King Jr.'s big speech "i have a dream". I thought that it was a very big worded, strong message that he sent out to the whole world. Plus it made me really think about how bad rascim was back then, and how slaves used to get treated or black people... When someone says rascim it makes me sick to my stomach because like, were all just regular people on earth, no body has more power or more rights just because the color of the skin,hair color,eye color,height,etc... So its not right to just go up to someone and judge them for something that was in the genetics.., or something that they can not physically change...
