The ignorance in the OP is typical of todays left trying demonize and vilify any who disagree with them.
The GOP does have a problem with educators though. I don't think it comes from some lofty disagreement on topics, but is more about motivated self interest. Voters will vote for the party that they feel benefits them best and right now for educators at all level, that's been the DNC.
A lot of the conversation on the Right tends to put the blame for issues in education squarely on the teachers, which isn't just unfair, but also false. It tends to brush right past parental and funding issues that plague a lot of schools. A teacher is going to have a rough time managing a large classroom that gets larger due to budget cuts, especially when kids come to school without parents helping with homework. Some kids are coming to school having not ate, not bringing lunch money, or missing crucial supplies. Then when those kids fail, the blame is increasingly put on teachers.
On top of that, even if a teacher has a class full of really active and involved parents, there isn't much you can do to prepare the student for the world out there if you don't have the materials needed. There are a lot of aging books that aren't being replaced which are filled with demonstrably wrong things. A lot of schools are struggling to even put one computer in a classroom. That's insane considering how important fluency with a computer will be for students.
Are there bad teachers? Sure. But in the ease to appeal to voters a lot on the Right go too far and demonize all teachers. I've met a lot of new teachers at all levels (K12, College). A lot of them started Right leaning or even GOP registered voters. And almost all of them will change over the course of a few years to Democrats. Why? If one political party consistently uses you as the bad guy, you're not going to vote for them.
BTW: This is the source of Trump's problem right now. Blacks, Latinos, teachers, college educated white males, are all starting to feel like Trump is specifically smearing them and he is starting to lose with them all. The Conservative vision is a better life for all people regardless of race, but the message isn't taken seriously when you advance it by demonizing some.
