I stumbled upon this web site the other day http://www.procon.org/
Actually I was listening to NPR.
From the site:
Our mission:
Promoting critical thinking, education, and informed citizenship by presenting controversial issues in a straightforward, nonpartisan, primarily pro-con format.
ProCon.org is a nonpartisan, 501(c)(3) nonprofit public charity
I have not spent a great deal of time on the site but so far it appears to me that they do what they say.
