The "foul-mouthed tweet" isn't quoted (in Portuguese or in translation), but I clicked through to Twitter and read: "Por que estão falando mal da buceta de 33 metros em vez de enfrentá-la com um pirocão?" And I have Google-translated it for you: "Why are they talking bad about the 33-meter pussy instead of facing it with a dick?"
I guess he's suggesting that opponents of the hillside ought to devise a way to rape it, or no, maybe he's just calling for equality and would like another hillside with a sculpture representing male genitalia. Google translates "enfrentá" as "facing," but also as "confronting" or "encountering."
Obviously, I am incapable of assessing the humor or hatefulness of a Portuguese tweet. One idea is to translate the responses at Twitter. For example: "Professor Olavo, you are a great intellectual and an exceptional teacher. But this compulsion for hostility and bad words related to sexual organs and waste are symptoms of psychiatric disorder. Try to treat yourself, your ideas will gain more strength!"
If you search for monumental constructions that represent genitalia, the vast majority of what you will find is male. Here's the Wikipedia article on "Phallic Architecture." There's no way feminist sculptors could ever carve enough concrete into hillsides even to begin to achieve equity.
For another example of a monumental vagina sculpture, see "The Dirty Corner," a gigantic construction at Versailles, by Anish Kapoor, who described it as "the vagina of the queen coming into power." The article at the link — from BBC in 2015 — quotes a random German tourist: "It's confusing, a big vagina and a palace. It's one of the most famous places in Paris and I just wanted to see it and I saw this building, this statue, and I don't know what it is." That sculpture has been vandalized, and Kapoor, who is male, has denied calling it a vagina: "I never said vagina—I said ‘she sits here on the lawn’ or something to that effect."
Ah! The difficulties of translation!
