I think it depends on the language you use. Most words in English have fairly specific connotations. Unique and unusual have differant connotations than wierd or strange. Saying you pity someone for their name implies that you think there is something wrong with it.
How would you feel if you came onto BB and found someone saying that you felt sorry for children named XYZ and you had named your child XYZ?
I don't think that using some tact should be a big ask.
