If we all stand around and wait for the collective action to start, it never will. imo start by making informed choices and sharing your reasons when asked.
Shrugging at brainworms being inserted into your child and shrugging with a "well that's just the world we live in" is mind boggling to me. Heck, when i grew up there were kids without TV at home. They survived pretty well, despite a bit of social disconnect.
