I was wondering when someone was going to try this argument!
Obviously, there's a lot to say here. Without rattling on too long, the first and most obvious point is that Disney has generally NOT been removing attractions to build new ones that might appeal to families with children. That's the OPPOSITE of what they've been doing. Disney has shifted to an emphasis on thrill rides, many of which younger guests (and older guests, and disabled guests, and unusually shaped guests) CAN'T RIDE or are less likely to want to. In fact, the new round of bars is precisely keeping with this broader shift in attraction design philosophy that sees Disney shifting to appeal to "Disney Adults" to the exclusion of many age groups, going so far as to pander by building attractions that that cohort has been clamoring for like the door coaster or a villains land.
