Azizi - That was a very interesting response to the square-dancing question, and what you say makes a lot of sense.

I would think that when square-dance was at the height of its popularity - before the era in which people became self-conscious about preserving or reviving it - it would have been danced in some form(s) in Black communities, but that those people and communities (where those communities still exist) have moved on in the ways that you suggest, without the desire to preserve or revive the past.

I've read interviews with Black blues harp stars of previous generations who've mentioned starting out in the south "playing waltzes" (the great Little Walter is one) ...

As a point of interest in this context, I have seen Black Canadians participating in "White" trad. folk culture when participation in the activity emerged naturally from some social context, activities including Irish dancing, singing & playing instruments in trad. folk music performance, playing Highland bagpipes & drums ... Not something you see often, but on occasion ...
