“Give me Liberty or give me death.” Patrick Henry.
One man with courage is a Majority. Thomas Jefferson
Or if that isn’t good enough...
Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen. Winston Churchill
If you aren’t going to join us in the first part of Winston’s sentiment... Sit down and listen.
