At some point they have to admit they chose the wrong side of a particular argument - if not from the moral standpoint, then from a business perspective.
Viewing their current audience and using them as a basis for decision making is only going to hurt them. They need to find a way to win back the other side and that very much means not doing what they've always done and *gasp* changing.
There's not enough people left on their side to survive.
I can very much see them going, right now, "well the guests in our parks love XYZ - we need to advertise more."
No, no you don't SeaWorld. You need to appeal to the guests who aren't in your park in a substantial way.
