Nothing magical about it. In both philosophy (ethics) and law, intent is an important consideration. When the intent is so clearly benevolent as in Chovie's story, then it seems a little over the top and lacking in generosity to label the old man a racist just because he doesn't know the currently accepted language. What is more, by using the "racism" term so liberally, the effect is to water it down to the point where it no longer carries any particularly negative meaning. Meanwhile, every time some poor old man, or a recent immigrant from eastern Europe etc. is caught being "racist", the real racists are having a field day, cheering and celebrating, gleefully anticipating the day when the "racists" become the majority.
