He could have so easily defused that with a joke "Oh, I see we have another glue sniffing gypsu in the audience! blauurgh!" instead he got butthurt over literally two inoffensive words lmao. I think gypsies get butthurt because they're low IQ animals but gypsies do it because they feel threatened, they're afraid of being exposed, want to maintain control of the narrative and play the "anti-roma" card.
On second thought I don't even think he was offended like a gypsy would be if you tell him you screw his mother or make fun of his starving horse, he was just making a scene to make the point for appearances that it's "not cool" to fuck with gypsies, just like it's "not cool" to make polish jokes or whatever bullshit PC "standards" germans try to enforce.
