If you haven't tested whether you are or not by saying no to the establishment or an authority, and then suffered significant consequences because of it, you have not made it into the initial screening of not being in the 90%.
So, just saying no to the establishment makes one part of the 10%
Of course, parents are everyone's first authority figures, and everyone says no to them. In fact, the more childish one is, the more one says "no" just to say "no." I just came back from visiting my grandkids, and "no" was their favorite word. The teenager is different. He just think he knows better than anyone over 25. Oh well, when I was a teen --and then teens were much more politically active than today-- the saying was "Don't trust anyone over 30." What I, and I guess many others, found was that our parents were often right; and what we lacked was judgment.
Anyway, afa the % stuff, imo it's silly to think that people (i.e., individuals) are so one-dimensional that their opinions can be cataloged to the point where if they believe one thing (such as that the gov't did or didn't do this or that) anyone can then tell what their opinion is on an entire catalog of issues. This applies as much to religion as to politics. 9/11 is not the same as Monsanto or big Pharm. Being a member of a particular sect of a religion doesn't mean that one agrees with everything that members of that sect do.
Afa the criticisms of "religion," personally, I think the criticisms are directed toward Christians and almost never toward Christianity or the words of Jesus. Most recently, I think ededed and others have criticized "organized religion" but the criticism wasn't aimed at any particular religion. (Btw, I disagree primarily because I think religion is just the fact that people will agree with a certain set of beliefs and how to practice them. So, if one wants to criticize, it would be better to pick something specific and illustrate how that practice is negative, like taking communion or baptism or worshiping on Sunday). Otoh, there have been numerous criticisms of Islam as a religion, per se. In the thread about the Zen Buddhist priest, the criticism is about what he did. But, having a harem of sexual partners or financial embezzlement and enrichment are not foreign to Any church. In fact, I don't even think it's foreign to any external or internal cma.
