Should there be two different sites for Y/A?

I do think it is time for two different sites for Y/A. I think this site should stay as is and a new site for adults 21 and over. I think rules should be about the same, except more leniency for content, topics and language. Teenagers are in a whole other world then a person who works, pay bills and raises children. Every person that e-mails me is an angry teenager, because they don't like an adult point of view or opinion. Should there be two separate sites???
