Typically we are encouraged to talk through our thought processes. This is often helpful in the context of friendships, personal relationships, and therapy sessions. A public forum where discussion about an important or sensitive topic is taking place is not the place to talk through the evolution of your understanding. It's okay not to know everything, and it's okay not to bring a fully formed opinion to every discussion. It's okay to listen and gather information and viewpoints, and then take the time to consider them, gather additional information, and then begin to form an opinion. Our society is so hell-bent on the "set it and forget it" mindset that we want to land on a conclusion, call it gospel, and move on without ever having to consider it again. It doesn't work like that.
