Art can be anything. Therefore art cannot rebel because art is already rebelling and conforming at the same time, two opposites which cancel each other out. So art isn't doing anything, although it's not doing nothing either, since my friends and I proved that "nothing" cannot exist. Therefore, with art not doing anything or nothing, it cannot help you here.
I don't think it works that way. I seriously believe that you would have a hard time prooving that Art can not be used to rebel. Especialy to Art critics or artists. You are using math logic to arts which simply is a big "no no". I am not saying that Art itself is a rebelling concept, but that it certainlt can be used for rebelling agendas. Most art works historicaly have been used for rebelling agendas.
That's how you rebel, not why. There must be a bigger goal, some kind of action that can be taken by what you're rebelling against. And you don't need major change. Gradual change can make a difference. One person out of billions making one action out of trillions can make a difference.
Art is fairly individualistic. Certain messeges don't need a large following. You won't hear an arguement from me that Socio-Economic rebellion needs something more active and direct than art, however Soaker users aren't important enough for me to do any sort of great physical action. For all I care newcomers can marry and start kids with Flashfloods. I simply could not care less. My beef is what hasbro has done to one of my childhood favorites. The Forums new ideology simply has only to do with my personal view about hasbro's change to Laramis line. Nothing else. I don't buy contemporary hasbro models, I do now modds, so according to your defenition, I would be already activly part in your version of rebelling against hasbro. Just that to me, its not enough stylisticaly.
Adult content is a weird way to rebel against dropping soaker quality. The normal inverse of small and weak is big and powerful. Therefore the normal inverse of small and weak soakers is big and powerful soakers. And how do you get big and powerful soakers? Right...
I'm not using anything other than simple logic here. That's all you need in life, other than money, status, and happiness.
Anti-thesis can go different ways. The evolution of abstract art would be the best evidence. I certainly still do the Big Powerfull soaker promoting thing, however it has been done(ICE BLUE COMBAT). And while I plan to do a "Powerbased Review site" later this year, very literaly actualy, there are other counter-movements to explore. The Mature soaker theme would be one of them. I am not counter-attacking low power only, but hasbro's new age group favorite which did their part on hasbro getting away with it. The Mature Theme has multiple symbolic angles.
One thing people have to keep in mind, Art isn't always about logic and common sense. And that can be sometimnes a very good thing. Thinking outside of the box or standards, sometimes means thinking outside of logic and rationality. The Brechtian Alienation effect would be one example.
