Saying that a country like Romania is not ethnically homogeneous is absurd. Gypsies exist but in low numbers and stay in ghettos. Muslims only exist in some countries of the south of the Balkans.
Dismissing facts as lies is just... something to say. Bolsonaro and his followers know this is true but they simply don't care. Which is a reasonable political stance I reckon.
I do, because I live surrounded by social housing blocks. And just last week they were lighting a campfire inside their building. After many years you can't imagine the things I've seen. Maybe it's you who doesn't know the kind of people who receive social housing.
