I find the biblical-basis tag problematic.
The tag wiki points to this question and its answer by David Stratton. The discussion was some time ago, and the culture of our site has changed significantly in the last 18 months; there is now a strong culture against "truth" questions, aiming more at the objective "what-does-church-X-say-about-issue-Y" questions. This change has been an enormously positive one and has improved the quality of questions and answers on this site.
I feel "biblical basis" questions are at variance with this culture. They ask for an answer that is not based on any theological tradition or doctrinal position. They encourage speculative/creative biblical exegesis. C.SE is not about these things. We have, if you like, a No Original Theology policy.
There is also the problem that these questions are inherently limiting. The "biblical basis" concept is most compatible with Reformed/Protestant/Evangelical churches. It is a method foreign to Catholic and Orthodox theology (and, to some extent, to Anglican and Methodist theology). It's sort of like saying, "based on trigonometry, determine how happy this person is." The concept of "biblical basis" does not acknowledge that it inherently takes a theological position. This is problematic.
I think we should require that people specify a school of biblical interpretation when asking questions about biblical exegesis. We should strongly discourage people from doing original biblical interpretation and encourage them to work explain how various theologians/exegetes/schools of exegesis have addressed the question.
