I speak reasonable Brazilian Portuguese and your translation is about right.Ok thanks, I speak some basic portuguese and will give it a go.
If Olavo de Carvalho was pro-abortion, defended the bandits, in favour of legalizing drugs, for gender studies, (torcida pela, not sure how to translate that). Then he would be known as Marielle.
That's it. I don't know the story behind or who Marielle is/was but certainly there is a lot more to the story.
(guess it's her Marielle Franco - Wikipedia)

It's Twitter left/right culture war stuff, and a footballer really shouldn't be getting involved in it. But it certainly doesn't show that Lucas supports/justifies Marielle's murder, at least not in that case
*A UK equivalent would be the celebrations around Thatcher's death.
