For Stamos to suggest more people need to think for themselves, that more need to question authority more, sounds naive, at best. That is the last thing the powers that be will allow. They're fine with misinformation, they just want to sure it's their's and no one elses.
The irony is this latest "scandle" will ultimately be solved with less individual free thought, not more. It will be a psychological / emotional / intellectual nanny state. No human neuro activity too small to micro manage.
Yeah, it sounds extreme. But so would The Patriot Act pre 9-11. So would Ed Snowden before we knew about Ed Snowden. Both of these were met with barely a shrug of the shoulders. There's nothing to be fixed from Congress' pov everything is as it should be. It just needs a slight bit of adjusting.
