who does not want to go out of her way to hide her nipples because they're considered obscene and offensive.

The OP could have criticized Ivanka or her father in legitimate, substantive ways. But instead, they chose to mock her because she dared to show her nipples. Saying that this is about hypocrisy is grasping at straws. This is about misogyny. You cannot attack a woman's -- any woman's -- appearance without being sexist. That is so obvious that it shouldn't require explaining.
