I think GMR and MMRR are significantly different and don't have the same purpose -- GMR wasn't just about putting you in the movies. That's why losing GMR was such a big hit to the original theme of DHS. MMRR may actually fit the new theme (such that it is) better, but the current version of the park is kind of aimless.
Regardless, my point was that if someone is mad about losing Splash for the reasons stated in the post I quoted, but wasn't equally mad about losing GMR, then it's hard to argue their anger isn't politically motivated.
I'm personally not mad about losing either, because they're theme park attractions. I'm disappointed that something I enjoyed (and was a design highlight) is no longer there, but there are many former attractions I like better than their replacements. I don't understand the outright vitriol. If it gets to a point that I no longer enjoy what's at WDW, I'll just stop going. I've only been twice in the past 10+ years anyways.
