Speaking Hypothetically

Why do we ask people hypothetical questions? We already know the answer and we already know it's us, so what is the point? For example, "Hypothetically speaking if a woman lets a married man digitally penetrate her vagina with his fingers, is that considered cheating?" We all know the answer to this one, yet we ask and hope that someone will tell us that our skewed moral compass is actually straight. If I think you are wrong, then I will tell you you are wrong. Friend or not, you have to be ready to get the truth as I see it. Sugar coating is for pastries, not truth.
