Citing equality doesn’t really fit, because they are not equal. Saying a woman should be paid as much as a man because a woman’s ability or intelligence is equal is not the same thing as saying women’s bodies, which are not identical to men’s, should be treated identically. Having a woman cover her breasts does not lower her social standing or make her to be inferior to a man.
Let’s turn the tables. Is the argument that a certain part of a man’s body should be censored because it’s different from that part on a woman a valid argument to you?
