So was Scalia pro-guns or anti-guns? Did he believe in the constitution? I guess promoting attacks on 'original meaning' would include those who are anti-constitutional.
Scalia seemed to advocate the notion of Judicial Restraint versus Judicial Activism wherein he didn't believe that much discretionary latitude was to be granted to judges. No, those advocating "original meaning" is in reference to the Constitution. It's not anti-constitutional, it's simply the different interpretation of what the Constitution means... Think: Spirit of the Law vs Letter of the Law. He was more a Letter of the Law kind of guy.
Some of the Justices see the Constitution and their role in defending it is fluid, dynamic, and should be viewed in light of contemporary issues. That would be more in line with Judicial Activism. Scalia, being of the Original Meaning/Judicial Restraint camp would say that the Constitution is rigid, inflexible and uncompromising in its protections in the sense that you never go beyond what it is saying by taking contemporary beliefs in to account.
