You raise some interesting points in Copyrighted and Extremist content. Both copyrighted and extremist (hate speech) are illegal and can (and some would argue should) be removed. However, it is more problematic if the administrator just does not agree with the political leaning of the writer.
I am cautiously optimistic that most of the visitors to the site will share similar interests with those who write on this forum. of course this is just wishful thinking.
