As an European I can tell you one thing.
I've never meet one single group, one single collective, as scheeming pathologically lying self-righteous and smug as gypsies.
They manage to get away with so much it's actually hilarious, where I live, like in most civilized countries, is a crime to not make your children go into the prisons we call schools, but somehow gypsies get away with it on a constant basis and still manage to properly fill them for citizenship and welfare programs, and oh yeah, the "welfare programs", if you're gypsy you're entitled for reparations.
Gypsies and slavs are singlehandly responsible for most drug trade, most theft and most human trafficking where I live.
They're so fucking problematic that they don't even comply with littering laws and where they live tends to looks like absolute shit as time goes on, they're like miasma, filling the place with disease, used needles and making the buildings around them decay faster (which makes sense, since they will no doubt steal all the copper wiring and forniture).
Don't even get me started about the inbreeding among them.
I don't care if it's genetic, caused by their cultural Zeigeist or both, gypsies are absolute scum and I apologize for pretending they would make good slaves, unless you heavily brainwash them they will never be useful.
