When we pay college profs a whole lot more than we do now, it will be possible to have a large enough pool to select for highly skillful teaching as well as knowlege of subject. I had a whole lot of truly obnoxious folk teaching me in college...but so long as they knew their stuff I was ok with them. Scientists, especially, do not suffer fools gladly and often are at least mildly afflicted with Asperger's syndrome, giving them few social skills.
As for k-12 teachers, they are not the to half of any college educated group. Few have a good understanding of the science they teach (for instance having students do "experiments" that are clearly demonstrations with right answers).
Those of us living in the real world, wthout an agenda to destroy science and replace it with theocracy, accept the limitations and work to improve, not re-define and destroy.
