I have watched perfectly healthy threads been closed by moderators for really really ridiculous reasons.

I still remember there was one thread, it started talking about science, but the conversation drifted a bit towards philosophy.

No matter it was about science or about philosophy, the conversations were still on topic.

Then a mod shut the thread down, citing that it was a science thread and now it had become philosophical.

How ridiculous can that be?

Just because of a tag (science) the conversation isn't allowed to drift into philosophy?

How qualified is that moderator in the first place to know if philosophy isn't related to science, or vice versa?

If this PhD section supposed to be for forumers to discuss high-level ideas, how come moderators who can't understand anything are taking charge over here?

At the very least please send moderators who can comprehend higher level of thinking to take charge of the PhD section.
