Having answered a number of questions and engaged in comments, my conclusion is that BHSE is hamstrung by two factors:
A lack of clarity in defining what Hermeneutics actually is. I've taken many classes on Hermeneutics itself, and classes applying hermeneutics. And, here on BHSE there doesn't seem to be any attempt at even defining what Hermeneutics actually is. For example, when there are text-critical questions that are posted in the Christianity SE, they are pushed over to BHSE. But, text-critical questions are neither theological/dogmatical questions (thus, appropriate for Christianity SE), nor are they Hermeneutical. They are, at best, pre-hermeneutical. TC gives us a text on which to base our dogmatics and hermeneutics. In practice, the prevailing path is basically: "this question requires Greek or Hebrew, and so it belongs in BHSE."
A lack of understanding the limits of hermeneutics. Hermeneutics was never intended to be a stand-alone tool. Instead, in conjunction with biblical theology (isagogics), Studying the source texts (exegesis), Historical theology, and finally Dogmatics, we finally arrive at a full meaning. Hermeneutics is a worthless tool by itself. As an example of this, I submit this.. It isn't very difficult to see that the responders to the question gave answers that overlapped both hermeneutics and dogmatics. For my own part, I have no problem with this. This is open and honest and natural. Again, hermeneutics was never meant to be a stand alone tool. My frustration is the clearly, obvious dichotomy that arose where, if one did not like the interpretation of the other, when exegetically (hermeneutically) both options might fit, the commentator voted down, voted to close, etc.
In working towards a solution might the moderators form a σκόπος, a focused preface as we see in the introductions to bible translations? These provide both useful explanations but also useful boundaries. Might the framers of BHSE make use of a preface to set forth concretely what discussions will be allowed and not, and also then why?
In practice now, (from where I sit), BHSE, on a good day, basically runs/behaves like a non-denominational forum for those with a high view of scripture (and varying degrees of original language training). On a bad day, it reflects the book of Judges: ”בַּיָּמִ֣ים הָהֵ֔ם אֵ֥ין מֶ֖לֶךְ בְּיִשְׂרָאֵ֑ל אִ֛ישׁ הַיָּשָׁ֥ר בְּעֵינָ֖יו יַעֲשֶֽׂה׃“ (Judges 21:25 HMT-W4). As an example of this, cf. This question. I can't see any reason why this wouldn't be a legitimate question on BHSE if decent boundaries/borders were provided. But the commentator adds the chiding, almost condescending words, "Such definition questions should not be considered a hermeneutic ques." He chides the questioner, telling him that his question has nothing to do with hermeneutics. But there is no definition as to what hermeneutics actually is. And yet, the commentator elsewhere transgresses his own self-chosen ("in his own eyes") criterion that he sets forth here.
So, please receive this both as a plea and also a question: What is Biblical Hermeneutics?
