You create a false dilemma. The helpful answer is the one that answers the question, and if you also want to suggest alternatives, feel free to do more than answering the question, but don't just question their motives instead of answering, because questioning someone's motives instead of answering is an antagonistic behavior. You're basically saying "I don't also want that thing, therefore you must be an idiot." That's an obnoxious framework to operate under.
