For someone who is experienced, yes it wouldn't take much time at all. But the fact that he was even asking means he was struggling. I am not trying to start a fight. I know you were just trying to answer his question but personally, your answer made no sense to me. I figured if I didn't know how to wire a dimmer, and neither did the OP, he would also not understand your answer. So I gave him a different solution.
I don't understand why you are trying to achieve by arguing about this.
