A wide variety of discussions and debates are possible here on the SDMB, provided that your opinions are in line with proper and agreeable thought.
It is possible to have interesting conversations about the details of gun control, provided that you are in favor of gun control.
It is possible to have interesting conversations about Global Warming or AGW, as long as you do not cross swords with the high priest and offend his religion. You will know him by his walls of text cites.
It is possible to have interesting political discussions, provided that you never identify as a leaning right at all, or heaven forbid, say that you are a Republican. Otherwise it is OK to talk about the various issues and why they are still Bush’s fault.
This place is mostly and echo chamber of correct thought. A couple of new moderators are having a very slight, positive effect to change this, but for the most part threads are moderated to reinforce correct thought.
Avoid The Pit, stay out of Great Debates and Elections, and you may find this place to be an amusing distraction, as I do.
