Ah, the typical teenage misunderstanding of the internet.... "it's the INTERNET, I can do whatever I want otherwise they're NAZIS oppressing my FREEDOM!!!1"
A website belongs to someone buddy. FaceBook is someone's property. If I own a website I can delete content on it as I damn well please if I don't like it - just like The Register deletes comments which it doesn't like.
A website gives you far fewer rights than the real world... no recourse, it's typically a dictatorship and you can't do anything to appeal.
