Honestly have no idea which side people are on with this hand holding thing but I’d like to just mention something people tend to forget which is Rey’s a loner, or at least fancies herself one. I figure that has more to do with the “don’t hold my hand” than anything else.
Watching J.J.'s film my interpretation was that this was funny that a white girl wouldn’t want a black guy to keep bugging her. It was a throwback. Not PC. I thought it was hilarious.
