what does FLCL try to portray in human society?

It takes a lot of guts to admit you are wrong. Good for you Mal.

Yanah, you should be more like Mal.

This is too confusing...
About the whole "real" being real thing I think that in oreder to have evryone believing the same thing
we would have to be sent into a virtual "past"
iuntil things kept advancing until we reached the actual time we are at really and by that time someone would have had to have discovered that it wasn't real by tthen. In my opinion what is going on right now is real what ever little fake world that you are living is just like a alternate reality that might exist until you syop thinking about it . so taking what I just said we could be in the mind of a four-year-old just expirincing the trials and tribulations that he wants us to . Then if he was to die we would all die causing all of our "imagined universes" to be destroyed which might cause the imaging imagined "universe" to be destroyed so on and so on until we reach a point where the universe of the child that destyroyded our universe is destroyed causing the whole thing to start over again in some aprodox-y way.
