Absolutely. I called one of my girlfriends who grew up and still lives in Georgia for her views on the subject because I was wondering if mine were just too strict. Her response is that she would probably faint if anyone asked her to remove her shoes in their home and would be appalled if someone came in to hers and took their shoes off. I wasn't totally surprised by her response as we both attended the same finishing school and come from similar backgrounds even though she tends to be a little more laid back than I am.
This sounds like a regional thing. In all my travels in the South, I have never been to anyone's home where I was asked to remove my shoes or where the host/hostess wasn't wearing theirs. Maybe it's an issue of formality. The Midwest and Western parts of the US have always seemed less formal to me. Not that that's a bad thing. I kind of like not getting dressed up to go grocery shopping any more.
