If there are any conservative public school teachers, I have never seen one.
To the contrary- just because you never saw or knew a conservative teacher, doesn’t meant they don’t exist! True, it’s been many years since my Mom taught school. However, I stand by my post. There have been and still are, a number of conservative teachers; though admittedly, not as many!
Maybe you don’t see them, or know of any, because you don’t want to? Think about it.
