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?
But I don’t think it is censored because it is different. I think there are reasons other than simply it being different as to why it is censored, and those reasons are potentially sound.
Women’s breasts aren’t just different-and-that’s-it. Men have sexual responses to them. Women have clothing that accentuates them. Women and men both treat women’s physical bodies differently than women and men both treat men’s bodies. Women have different attractions to men than men do to women, and so arguing that men’s bodies and women’s bodies should be treated equally (or identically) “because” isn’t reason enough to not treat the differently.
I don’t think turning the tables like that works, because you’d have to turn the tables on other contributing factors, several of which I have no experience with (like the psychology and sexuality of women).
