I think the fundamental problem with your analysis is that it treats "belief" as a binary rather than continuous valued attribute, which is inappropriate even for fairly simple claims where belief can be less than absolute, and it is certainly horrendously inappropriate for complex claims like "that a system of government is an effective means by which to manage a group of people living together."

A secondary problem is that you conflate belief that a system is "an effective means" (your first paragraph) with the belief that it is "the most effective means" (your second paragraph). These are obviously very different beliefs.

> It should be an indication to you that you find such an idea to be negative in the first place when Snowden is brought up. Why exactly do you think it's so negative that I say he doesn't believe in the US system of government?

I never said I found it to be negative. Saying that I think the logic of your argument is invalid is not saying I believe the statement it was offered to support is negative.
