Try putting yourself in her situation: if a bloke approaches and basically says "suck my dick?" then I think it's fairly safe to assume he's a potential threat. Better safe than sorry.
Sure, it's fair to assume he's a potential threat. If someone hells "hey douche-bag" at me, I assume there's a potential threat.
But no threat is being made there.
Next thing I'll know, ten-thousand people will be arrested for saying "kiss my ***."
