"I already battle teachers! And I do it when they are liberal OR conservative."
You battle liberal teachers? How? By voting down school budgets?
You battle conservative teachers?
How? There are harldy any. And why would you if there were?
It depends upon where you live. If you're in a "red" area, many of the teachers are conservative.
By being in actual classrooms and contradicting what they say! By expressing my views to my college professors and my fellow, (almost teacher) students. I tell other parents about my experiences in the classroom so that they can be prepared.
Actually, I'm doing quite a hell of a lot to solve the problem that you claim to be so concerned about. What do you do?
