Douchebags like you are ruining San Francisco

I dislike the fraternity culture as much as anyone else who dislikes it, but it's not much worse then any other kind of cultural baggage like-minded groups of people bring.
Sure, I like the image grit and sticktoitedness that might have been associated with immigrant waves of yore --but now not all immigrants are from economically deficient backgrounds --sure, there may be still the dispossessed but we also have those with possessions or inter-city or inter-state migrations to SF people looking to get rich quick -ala Wall Street back a few decades ago.
SF doesn't 'belong' to a time or a people and place, it belongs to its current inhabitants --they shape it, that's it. Stop being possessive about something which is meant to change with time. Paris of today is not the Paris of the 40s, etc.
