If forced to use my real name, I likely wouldn't participate in the comment sections on topics that I care most about. My boss is a political extremist and I disagree with him on 90% of issues. I keep my mouth shut at work because he's a loud, aggressive bully and I need my job. 

I know I'm not alone in this concern. I believe in allowing people to keep their privacy online, especially since there's no way to prove "real" names, anyway. Even if I chose "Alex Smith" instead of LynxCreek, there's no guarantee it's my real name, so honestly, what's the difference in the end? Judge people by their behavior, not their moniker.
