I don't find the song offensive, it is like anything else a time and a moment to the author. Rows and rows of houses all exactly the same. The urban sprawl. I find it no more offensive than "red velvet steering wheel covered driver" that one would think is a slam on all older people. It is a moment in time frozen by the author. I never liked little boxes ... But there is no doubt the impact she had on folk music. If I like the song I will sing it, if I don't I just ignore it.
