I'm quite surprised that so many don't realize that there exists an entire category of people that are not radical, but do hold opinions on some reforms that should be taken, including the quote that started this conversation "our ineffectual administration".
Speaking of ineffectual administration - I think it might be hard for some people to grasp that any bureaucracy is going to look inefficient. The point of bureaucracy is to replace ad-hoc decision making with a repeatable, documented, audited and justifiable process. Ad-hoc "the dictator decides" is always going to be faster.

This is the 2nd post ignoring the fact that I have declared I am, in fact, not a member of such a group. Assuming that I'm lying, you'd be correct in holding your stance. Considering I am not lying, you are basically closing in the door to communication and possible expansions of subject matter from someone that's really not an extremist in any sense of the word.
