1.) I grew up in the rural South, and was literally harassed for most of my career for saying "y'all" and "folks" but glad to see it's trendy to speak that way amongst the exact kind of people who used to assume I was ignorant for speaking that way.
2.) Your statement could just as easily be, on a different day: "Y'all abandoned the city for the suburbs and deprived the city of a tax base to help the poor." Between "white flight" and "colonizer/gentrifier", you're damned if you do and damned if you don't. Same applies to livability: If you demand quality of life crimes be dealt with to make a city cleaner, you are guilty of not "embracing where we were and not trying to change it".
Your entire statement to me seems driven by emotion and nostalgia without thinking about the fact that there are low income children who have to grow up in these places. Maybe parents aren't thrilled with having their 10 year olds learn the valuable life lessons of "how to not get knifed by a junkie in an alleyway".
Sorry, but the whole comment reeks of luxury beliefs. I've personally (in DC) been mugged at gunpoint (they threw me onto the pavement in the process) and had a random guy jump out of his car to assault me because I walked in front of his car in heavy traffic (all cars stopped) to cross a street, and he viewed it as "disrespecting him".
Real, actual victims of violent crime don't think it's cute or have this nostalgia for squalor. Beliefs like that are luxuries for certain kinds of people who are insulated from the worst of it, one way or another. It's easy for a childless bohemian to have no problem with needles in parks, but for those of us raising future citizens, it's not fun.
