However seeing as how this is not America and in fact is the private domain of the owner of talkbass.com it is a privilege to use it, it is up to the discretion of the moderators, administrators, and owner of the site to determine whether or not a thread will remain open.
The first amendment of the US constitution does not apply to the internet.
Edit: That being said, I don't think this thread violates any of the rules of the site, so it should remain open, but if it's closed, it's the right of the people mentioned above to close it.
