The following question currently up on EL&U illustrates the problem exactly:
I'll leave it to Janus Bahs Jacquet to illustrate what's wrong with the question:
What is ‘beliefs and value’ supposed to mean? You can’t just put two random words together with no context and then ask if there’s a word that expresses them – why should there be, if they’re just random words? There isn’t a word to express ‘sheep and coffee’ either.
So often this is the case. Question-askers assume there simply must be one single word to express two (or more) disparate concepts. (One wonders why they have such a burning need for this kind of economy and precision when the rest of their prose so often demonstrates neither.)
Similarly, the antonyms tag is full of misguided requests (often an effort to name categories in software applications, such as Antonym of outcast). In many cases, the question assumes that for every noun or verb in English there must exist an exact, perfect antonym. What is the opposite of "bottle"? Of "to fry"?
To make matters worse, such questions often invite a flood of attempts to answer. Often these are one-word answers, or nearly, and often they are not even remotely on the mark.
I think we need to step up and close such questions as "primarily opinion-based"—for that is what the rafts of guessing-game answers demonstrate—more promptly and completely (in video game parlance, even four close votes leave a question 100% combat effective). Either that or establish a new closing reason that addresses them more specifically.
