If a man “loses” a modesty debate, nothing about his life changes. If a man “wins” a modesty debate, nothing about his life changes. But if a woman loses a modesty debate, the entire fabric of her existence changes. If a woman loses a modesty debate, she has lost whole areas of freedom in her life. She now has more things to worry about not doing so that men will not get aroused. There is no such thing as an “objective” argument in which the stakes are astronomical for one side and nonexistent for the other. Furthermore, by even accepting modesty as a valid area of concern for women, you have accepted a premise that defines women by their looks and objectifies them. Women have already lost the moment a modesty debate begins.
