Thanks Art, I admit that I've given no thought what so ever to "songs that are commonly sung in Irish, Scots, Swedish or German accented English".
With regard to "songs that originated, among enslaved Africans or their immediate descendants, enslaved or not" (I'm talking about "dese", "dos", "gwine" and mammy type talk), I would say this:
1. Imo, it's not only appropriate, but it's important to have written records of how those songs were sung regardless of who composed them or who sung them
but
2. I think that it's also appropriate to post a one time statement in those threads which would say something like that these songs may contain language forms or dialect that has been retired (meaning that African Americans don't use language anymore and/or some people may consider that dialect to be culturally insensitive). Imo, such a statement should include something about the purpose of the song/s being posted on this forum.
3. I also believe that it is appropriate and desirably for there to be discussion in such threads about whether these types of songs (including spirituals) are still sung that way by most African Americans and whether they should be sung for entertainment in public settings, including public schools.
4. I also wish that the same type of statement or a similar type of statement would be posted one time by the thread starter or a Mudcat moderator on threads such as that China man thread whose link I provided earlier. In addition, I have come to believe that I should have posted a statement in the Down By The Banks of The Hanky Panky" thread when I found that examples were being posted that have "homosexual" referents. In response to those examples, I wrote that I don't think people should call other people "gay" (as an insult), but maybe that isn't enough.

On the taunting rhymes pages of my website I periodically post messages in bold font such as this one:
These examples are posted for their creative, folkloric value. I strongly advise against using these taunts & insult rhymes in real life situations as some people may get very angry or hurt because of what you are saying. In addition, reciting these taunts in the wrong place & time (such as in schools) may lead to consequences from school officials and/or other adults, children, or youth.
However, I'm aware that many of my web site's readers are children & youth. So I'm not suggesting that the same message would be appropriate for specific Mudcat threads.
