What you percieve as reality is real, to you.
Its... this is the basic functional mechanism of propoganda, advertising, marketing, etc.
It does effect people.
No one is immune to propaganda.
That's like, the entire problem.
You might as well just say 'the internet doesn't exist, you've never seen a movie or a tv/netflix show, you've never seen an advertisement.'
That's about as absurd as what you are saying.
Also how do you know this isn't genuine?
How did you determine that?
Is... everything you don't like, a psyop?
