Seemingly out of nowhere, he called on a family court judge to investigate whether I and my husband, David Miranda, a congressman for the Socialism and Liberty Party, are taking proper care of our two adopted children. A judge should investigate, he argued, since we both work.

But that attack on our family did not come out of nowhere. President Bolsonaro has long featured anti-L.G.B.T. animus as a central weapon in his political arsenal and has repeatedly used anti-gay attacks against me. He and his allies have attacked other journalists and activists who oppose him .

During the last six months of The Intercept’s reporting on Mr. Bolsonaro’s government, the right-wing leader not only repeatedly and publicly threatened me with prison, but also explicitly accused me and my husband of having a sham marriage, and of having adopted Brazilian children as a fraud, in order — he claimed — to enable me to avoid being deported. With that ugly history from the president himself, Mr. Nunes’s attack as retaliation for the journalism I’ve been doing made complete sense.

On the program in which I appeared with Mr. Nunes, I told him on the air that his was an act of cowardice, because he’d never call for a similar investigation for the millions of heterosexual couples with children who both work, including his own bosses and colleagues. He then physically attacked me, and the video of the attack quickly went viral on social media within Brazil and outside of it. I was not hurt, but the reaction in Brazil to that incident speaks volumes about the imperiled state of press freedoms and democracy here.

While mainstream journalists and political officials from across the ideological spectrum denounced Mr. Nunes’s attack, the leading figures of the Bolsonaro movement, including the president’s two politician sons and his “ guru ,” Olavo de Carvalho, explicitly cheered it. That the violence against me should be worse the next time — not a slap but a closed-fist punch or worse — was a common theme.
