I'm a huge believer in the second amendment. I believe that the right to bear arms should remain protected. At the same time, I support gun control. (Yeah, it sounds contradictory, right?) What this means is that I support the right to own guns, but, at the same time, I don't believe that any individual needs to own an Uzi.
(Of course, right now, I'm also thinking that an overthrow of government is needed, a la Declaration of Independence. So maybe those AK-47's and Uzis would come in handy. :P)
As far as lifestyle choices, I believe in the right to choose (abortion). I believe that same sex couples should be afforded the same rights and protections as everyone else. The government should not be allowed to manage our personal lives in this manner.
ETA: While I'm pro-choice, I can't support late-term or partial birth abortions. They can survive outside the womb, so let them. That's when I'd consider it murder.
