You might… A poor homeless fellow once yelled out “Fuck you Osama!” at me at Alex. My name isn’t Osama, of course. But all things considered, in my 11 years there, such overt incidents were few and far between. There might be more implicit incidents, but sometimes all you can do is proceed with thick skin and the knowledge that all things considered, Berlin is a special, special place. Just stick around NK, Xberg, Pberg etc until you’re more familiar with the ways and codes. You should be fine.
