If someone asks why so many young dancers learn ballet, I can say "signalling" and consider the question answered without having to engage with the availability of instruction, tradition, structure and organisation, how ballet differs from other forms of dance, or really engage in any detailed exploration of the subject at all.
Whether you actually believe, for example, a subjugated group in society should have all the rights and freedoms of it's majority, or simply believe saying that will net you social capital, doesn't change whether they do or not, and also doesn't change that such a message is probably, on balance, good to have repeatedly broadcast even if the speaker doesn't believe it with their heart and soul.
