@AoG - JtH had the right of it. If you phrase your question in such a way that allows for a one word answer, then the fault is yours, not those who choose to answer.
Your OP seems nonsense to me. It is no trouble, no effort at all to type "yes" or "no". Nor do you get to dictate how others on this site choose to answer, be it brief, expansive, provocative, argumentative, rational or irrational. Thats their choice, not yours.
If you want opinion or debate, or more expansive answers, spend a bit more time phrasing your question in such a way that a one word answer is not possible. If you want to stimulate debate, then the onus is on you to phrase the question, not the people who respond.
