This is a false equivalence. The reason people make fun of Trump for being ugly is because he himself mocks others based on their appearance -- particularly women. This is akin to queer activists in the 80s outing closeted gay Republicans who were advocating for anti-gay laws.
Turnabout is fair play. If Trump doesn't want people to make fun of him for his physical qualities, he shouldn't do the same for others.
