These sorts of questions are better suited to Worldbuilding SE. There, writers of any medium can ask theoretical questions pertinent to the fictional "world" they are creating. For example, I could ask about how having 5 moons would affect tides (astronomy/geology), or whether human would survive and be able to walk upright if a grow-ray zapped her to 20 meters tall (biology, physiology). Here's a popular question from just a few days ago: How can powerful telekinesis avoid violating Newton's 3rd Law?
In some ways, the site helps indie writers do exactly that - avoid having to pay an expensive subject matter expert consultant - for minor fact-checks when designing a fictional world or story. There are a lot of how-to's and it's a very rich SE community.
It brings together expertise from many fields to help writers build more realism into their stories.
I think we should discuss with the Worldbuilding mods about migrating to them the few we've gotten so far on MedicalSciences (only the ones that are on-topic there too, of course). And then we can consider closing the other ones. Although I haven't seen a lot of medical-related questions there yet, I would try to answer them myself if I saw one there, and would encourage some of you from this site to check it out as well.
I agree with the "potential harm" questions being concerning and those I would not recommend migrating, and would recommend closing here as well. Because this is an INTERNET community, the question/answer will hang around indefinitely and be searchable, and potentially be accessible to someone who might actually plan to harm.
