That does make sense to me, and I feel the same way reading through the Disney side of this forum (which is the only Disney one I still follow). Specifically, there seems to be a mix of those who generally want to discuss and critique the Disney parks but almost every thread has its fair share of posters who reflexively post negative comments and who seem to want to troll Disney more than they care whether it gets any better or not. In particular, a kind of laughing, mocking, and gleeful tone every time something doesn't work or falls short of phenomenal. I don't know the extent to which this is due to things Disney has done, social changes, or something else.
Anyway, I can imagine feeling the same way about people coming on here and critiquing Universal. From my side as someone who is honestly more of a Disney theme park fan than a theme park fan as such, I have found all the "this is really giving Disney a black eye", "Disney is panicking!", etc. talk part of the general noise over on the Disney side of the forum. That's why, when I look at everything coming out of Epic Universe, I find it hard not to think that it has a lot to recommend it, but if this were a new Disney park people would be howling about a lot of things rather than claiming they had outdone themselves.
In short, maybe toxic in the community is ruining everything for everyone!
