Recently, I wrote a question (you can see here). Which doesn't involve finding the value of an expression, nor a difficult calculation.
The first thing: This should not be considered a "homework and exercise" question. Since, this question is nowhere in an exercise; it is purely conceptual.
The second thing, my question was closed. I don't know why; I asked question very politely, and it is not even a "check my work question", or nor I am asking you to find the value of $x$. I asked about a concept involved in it.
Why do these ruthless people consider closing my question?
80% of my asked questions are closed here. I see many higher physics problems (even numericals) on PSE are not considered as homework and exercise and are even open, but high school-level questions have no value here.
Where should I (and people like me) go? Is there another Stack Exchange site that gives value to high school-level question?
Isn't it like politics in the field of studies?
