Do you think society KNOWS( not cares) that most everything they see on tv is a manipulation of some sort?

Manipulation of reality, yes.
Manipulation of them, no.

Do you think Hollywood has any kind of “agenda” behind the scenes?

The agenda is to make a docile population that consumed the targeted materials.

Are you aware of all the “Illuminati” symbolism in Music, Movies, Tv, etc. And do you think it means something or it all just imagery in light fun?

Talking about it is a waste of time, but yes, if it's intentional or just for a laugh we cannot say for sure, but regardless I prescribe to the killimunati ideology, as in cut that bullshit talk out as it's not doing anything to improve the world.
Elites stick together, we know that, it's not a controversial thing.
