Agreed. We seem to have a situation where the silent majority has morphed into the loud minority. Take schools, for instance, numerous polls (previously posted) have shown that parents like their kids' teachers and what's being taught. But we have a group disrupting school board meetings, threatening board members, and trying to create a wedge issue against public schools.
We can, maybe, remember, during the various town hall meetings about the ACA, much the same scenario unfolded in many locations, a disruptive minority getting the attention. They were mostly so-called astroturf groups, claiming to be natural eruptions of peoples' real feelings, but were actually bankrolled by the big money crowd.
And then go back to the Brooks Brothers Riot in Florida, it worked there on behalf of W, so it's in the playbook. Make no mistake, the goal is to privatize education along with most other government services. Which has worked well exactly nowhere else, but like the zombie theory of trickle down economics, it remains a powerful force.
