I understand everyone has an opinion, I also understand it is your "right" to express it; my question is why do you express it? Are you hoping to change someone's views, find common ground, validate your process, degrade someone else, create an open dialog?

I ask because recently I've been subjected to others uninvited/unwelcome opinions and it got me thinking about why they felt the need to share their thoughts and opinions, what they hoped to gain from it. Why they believe their opinion has any relevance.
