I'd like to ask if people think a law should be instituted in certain circumstances. Is that an acceptable question on the Law site?
That might be a good question for Philosophy or Politics SE, but not for Law. It is essentially outside the scope of law, which is the descriptive field of "saying what the law is". That would include questions about the logical mechanics of a hypothetical law, such as "Would a law X be constitutional, in light of the First Amendment". There is no legal standard for judging whether a given law should exist, so there is no objective standard for deciding whether the correct answer is "yes" or "no". If you have a specific issue in mind, you might ask about it on Meta and we could make suggestions about how to avail closure based on the question being a call for opinions (frowny face).
