What are some ways atticus finch shows equality in the book "to kill a mocking bird" and what are some quotes?

He shows equality by defending a black man even though he would be judged he knew it had to be done."The one place where a man ought to get a square deal is in a courtroom, be he any color of the rainbow, but people have a way of carrying their resentments right into a jury box. As you grow older, you'll see white men cheat black men every day of your life, but let me tell you something and don't you forget it - whenever a white man does that to a black man, no matter who he is, how rich he is, or how fine a family he comes from, that white man is trash."
