I don't think that they disagree that security should be a consideration, just that the risk for most people of walking from one's garage into one's house is probably not as high-risk an activity as your post made it sound. Yes, we women do have to be more cautious, and that stinks, but I for one know too many women (who live in generally safe neighborhoods) who are scared to go *anywhere* alone at night, even in a personal car, and that's emotionally crippling.
My neighborhood has some issues with property crime, very true, but we haven't had an assault on a person in this area (other than domestic battery) in several years. My garage opens on an alley, but it has a walking door leading directly into my fenced back yard. Most of the time I don't use the walking door because I have to squeeze past DH's bumper to get to it, but it's there, and any time I get an "off" vibe I can choose to use it. The thing is, having just driven in via the alley, I can normally easily see if anyone is in it, and 9/10 times I do see someone it is someone I know, so most of the time, and certainly in daylight, it's plenty safe.
Look at it this way: if the odds of getting assaulted in the walkway to your home are lower than those of getting into a serious car wreck on any given day, are they still unacceptably high -- so much so that you would base your choice of home on that?
