Her video got many dislikes because Anitta once positioned herself against a racist, homophobic misogynist politician (which happens to be now the president of Brazil), so his followers started an online campaign against her. That happened at the time of the elections in Brazil and many Brazilian artists who positioned themselves against him were "attacked" online like this by his followers.
Since most of brazilian music doesn’t have translation it would be nice if you guys take a look at the lirycs after reacting to the video. I really like to see when people check the content after all and get the meaning. Can you guys do that with Dona de Mim by Iza?
