In my experience, the only time questions were discouraged (and almost always in the interest of time) was because it was otherwise possible to get an answer to your questions.
Can you give an example of the environment you would be talking about?
A lot of high school teachers know little past what they are actually teaching and even that not in a lot of depth. This is for a lot of reasons, some of them not their fault, but it is a sad fact.
So, keep asking and keep annoying them. Try going and asking during their office hours, but don't be surprised if you do not get a satisfactory answer and if it does not seem satisfactory, I would question its validity.
Keep in mind though. High school teachers are mostly overworked. Even the ones that know what they are talking about (some don't - we established that already), so do cut them some slack and be curteous. But keep asking questions. And if they don't answer, ask anyone who will. Read, explore and keep learning. It's what keeps us alive and what - at least according to this post - keeps us smart.
Good luck and you are on the right track to greatness.
Interesting choice of words. Office hours are the "teaching environment". The classroom is the (increasingly obsolete) bulk information transfer environment.
But to echo the other reply, get out, life's too short to bother with that.
