Once again, arbitrary "moderation" has risen. A perfectly on-topic question was asked but was then moved inappropriately to another board. If I could formally register a complaint, I would, but I've seen here that people are usually punished for speaking out. This forum consistently shows a disdain for anything related to educational aspects of physics and astronomy.
It is unfathomable that a topic for which a tag exists can be considered topic. It is just as unfathomable that moderators can choose to ignore the established framework and throw out questions that they personally don't like or personally don't agree with. Simply.....staggering.....there is no stronger word I can think of for it.
There also seems to be a consistent bias toward users with sky high reputations even though they give bad answers. It's very difficult around here for newcomers to establish reputation amidst the bias and arbitrariness and willingness to accept any answer without even knowing whether it answers the question that was asked.
