These are my personal thoughts on the word no.
It’s a short word, among the shortest, but in my opinion, the word no is the basis of American society and has been since the beginning. All of your political rights are founded on the right to tell the government no.
Don’t like the current government? Say no and vote for someone else.
Don’t want the police to search your home without a warrant? Say no; make them get a warrant supported by probable cause.
Don’t want to sit at the back of the bus? Say no, and, eventually, your rights will be vindicated.
