When it comes to an issue like getting an amazing attraction that everyone's been waiting for for several decades (i.e. The Little Mermaid), then yes. Today as fans we need to pick our battles.
That doesn't mean that theme isn't important, and I do wish that those calling the shots would be more careful with it. It's unfortunate that they have no interest in letting WDI put forth original attractions that have no tie-ins to current Disney franchises.
