If that's the reason, then her heart might be in the right place.
This "club" sounds more like making a point than a legitimate ethnic club, where people sit around to share their ancestral music, language quirks, unique cuisine, inside jokes, cultural dances, etc.
When I was in college learning French, I visited French-American clubs regularly to get a chance to learn French nasal vowels from natives.
I remember a lot of camaraderie and good will among people of difference races who were bonded by their common Gallic background. . . food, wine, religion, chansons, literature, unique humor. Those clubs are still around. The same can be said about the other ethnic clubs that I visited.
I’m just having a hard time visualizing a Caucasian club meeting without the adjective boring coming to mind, but I could be wrong.
I wouldn't go, except to hack off people who threatened my freedom of association. After the club is grudgingly granted the right to exist, the fun would all be gone. Hopefully, this young lady has come up with a way to show school adminstration officials just how far they've bent backwards to encourage racial separation, and maybe they can just get back to getting kids to join the Chess Club, whatever their heritage.
