The crime statistics don't lie, and it's not going to convince anyone to dissemble or equivocate about them. Even the above poster's post is instructive; in the suburbs, you can generally leave a bookbag in a car for a bit without it vanishing.
Where I grew up, people left their doors unlocked at night a fair amount of the time. My folks didn't, because we were Philadelphia transplants. But others did.
I think the anti-urban bias rests on a bit more than fear, and I think it's dangerous to just pooh-pooh it as a symptom of a bunch of intestinally effeminate yuppies. There is crime. There are definitely poor schools; if you have three kids, you get a lot more for your money buying a 4-br house in Hillard and sending your kids to Darby or Davidson than buying a 4-br house in a neighborhood of Columbus that you could afford and paying for three kids to go to private school for 13 years. There are neighborhoods of Columbus that practically look like suburbs, so there's not so much of a shift when you cross into the real suburbs; you certainly wouldn't get an "urbanist" lifestyle living in many areas of Columbus. There are places with boarded-up buildings, cracked sidewalks, and, yes, drugs and guns.
We've managed to carve out a comparatively small island against that kind of thing in the central neighborhoods, and that island is spreading. I'm as bullish as anyone on continuing to spread it. However, compared to the whole length and breadth of Columbus, we have to keep in mind that the experiences and lifestyles of many on these boards are not representative of Columbus generally.
