In a way I actually agree with nearly everything you say, I just think you haven't taken what you say to its logical conclusion.
The thing you seem to be missing is that there are no “neutral” beliefs. There's no “middle” in terms of ideology. Doing “nothing” is de facto maintaining the status quo, and acting to maintain the status quo is a positive action just as much as acting to abolish it is. The belief that the status quo should be maintained is a positive belief just as the belief that it should be abolished it is. Right?
The thing is, by the very nature of ideology, those who wish to maintain the status quo rarely have their beliefs subjected to the same level of scrutiny as those who to abolish it. Therefore it is very easy for those who wish to maintain the status quo to believe that their beliefs and actions are sane, rational, reasonable, etc., because everything seems to reinforce that, while those who wish to abolish it are often portrayed as insane, irrational, “extremist”, etc., and as someone who does wish to abolish the status quo, it's very hard not to internalise some of that. Being constantly bombarded with that, having all of your beliefs constantly scrutinised from every angle inevitably manifests itself as incapacitating self-doubt that's very difficult to overcome sometimes. Sometimes the only way to cope with this is to temporarily suspend this constant questioning of everything you believe in.
It is far more common that people who wish to maintain the status quo are slaves to dogma than that people who wish to abolish it are. Often, the latter do not have a choice about whether or not their beliefs are rigourously questioned every five minutes. But the former can comfortably go their whole lives without ever having their beliefs rigourously questioned by anybody.
Edit: I think an NSA agent participating in these programs out of a belief that they are “serving their country” and who refuses to question what “serving their country” actually means is a slave to dogma. I do not think that somebody who believes that their communications should not be monitored or recorded without their consent and who refuses to question that belief is a slave to dogma.
