If you're not familiar with him, read the article, he's the founder of the MPAA and the ratings system for films in America. I don't necessarily agree with the way the program works, because I don't believe age is a clear indicator of maturity level, and is simply "the most effective" yet still not appropriate manner of handling the issue of censorship.
Personally, I don't believe in censorship at all, it's the foundation of government. If there were no censorship, there would be no source of government, because that is the source of the foundation of it. I'm not an anarchist, but adding these little restrictions on our culture has shaped it without the citizens' main consent, and rather a government agency, not something that usually mixes well for the interest of people and their freedoms overall.
