Government Surveillance Acct:   The Deep State is not grassroots. Didn't you say above somewhere that the Deep State was the "establishment"?
All participants in government, elected or hired, have very well defined functions. These definitions are devised so that the people who perform the functions do it properly, do not exceed their authority, do not interfere with other functions and do not neglect their responsibilities. 
This ordinarily does not mean that they can't have political opinions. But it does mean that they can't act upon those opinions except within the constraints of their defined function. 
What they can't do is act against the interests of the US as defined, for example, by the Executive Branch. 
The Deep State does just that. They collude to undermine i.e. subvert the policy of the elected President even when they have no mandate to do that. 
This is the anti-democratic aspect.  A very dangerous development.
