The Revolutionaries in the late 1700s wanted one thing: Freedom from England. I'm sure that Samuel Adams was originally in a very, very small minority when the idea first started to spread. Just look at what happened then. Our forefathers were irate at the way England was trying to take advantage of the colonies, so they (read: the minority) mobilized an entire people to fight for what they believed in: freedom.
LGBT populations all over the United States are now shouting to be recognized as equal citizens, to have equal rights, and to end discrimination against them. Hispanics are experiencing discrimination simply for their skin color. Sound familiar? Sure, it may seem like a minority to some. But just wait. Brush fires are being set. A new civil rights revolution is in the works. And before you know it, the outcry will become the common cry.
...and liberty and justice for all...
