idk if I'm just missing context but her behavior seems extremely weird and out of left field. why did she suddenly go off about "hipster bullshit" and say you were "making it political"? at what point was anyone talking about politics? that seems like a complete non-sequitur. I would be just as confused as you are tbh, but I don't think you did anything wrong. if she knows the guy and his issues then I'd get her being overprotective but it sounds like you don't know for sure.
