The basic problem - set aside that in your estimation, this guy is extra creepy - is that flirting requires violating social code. Period. Full stop. By any HR manual you care to consult, there shall be no fraternization at school, work or church, between providers and clients, between friends and neighbors, and ugh oh god who wants to meet someone at a bar they're so sketchy.

Which means - set aside that in your estimation, this guy is extra creepy - that Western society effectively depends on people brave enough to risk a harassment charge in order to forward the development of relationships and families. I'm sure you've been through your fair share of cringe-worthy sexual harassment training at this point to know that the the gauge for "unwelcome attention" is "when the other person says it's unwelcome." But that's not what's happening here. The other person's brother is telling HR to tell you it's unwelcome.

Your bag boy example is of an establishment you've avoided for ten years rather than tell someone "could you leave me alone, please?" In your example at the goodwill, it didn't even get that far. This isn't a case of not taking a hint, this is a case of three sentences exchanged.

And yes. My friend's 11-year old was being a vindictive bitch. But just like you live in a world of creepy 300lb Goodwill loaders, we live in a world of vindictive 11-year-old bitches. You? I mean, your honor was insulted by a male of a lower caste and now your brother is demanding vengeance from his liege-lord. you might as well just put on the fuckin' niqab and be done with it.

I don't understand how it can be feminist to require a world so nerfed-out that you never have an uncomfortable conversation with a male.
