It only looks that way because people tend to only notice when their "side" gets the smack-down. I've seen complete arguments conversations get removed from this thread so I can assure you, it's happening to both "sides" in this debate when people cross a line.
Regarding politics and "biases" in general though, it helps for everyone to remember where we are. There are far better and more productive places to argue talk past debate others about political issues than a Disney fan forum.
For anyone here who feels their views on this subject are being censored, I'd suggest finding another outlet out there to discuss/argue it.
I'm not saying if you don't like it here, leave - just maybe consider voicing your views and opinions on this particular subject somewhere else more appropriate for political debate.
