What is the most messed up US Supreme Court decision in history?

It doesn't have to be really outrageous or controversial, but had a dramatic impact on society. Thank you!

The person who started this is dead, and so should have been the subject. Now I have to fear if my beliefs will be osterisized if I walk out of the house.

I will still pray in a restautant, I will still that the witness stand and say "So help me God." I will still teach my Grandchildren humility in the presence of God. The courts will never stop me.
