The Dolphins remind me of when Port Adelaide joined the AFL comp. They set up a new entity separate from the Magpies who were granted an AFL license. Collingwood forced Port to have a new nickname (Power) and new colors (teal), and no black-white stripes. They entered as Port Power, with a horrible jersey and trying to more embrace the broader Adelaide fans as a second Adelaide team. After a number of years of backlash and own confused identity, they realized it was a mistake. They eventually took to re-uniting the Magpies and Power as a joint entity, they changed their name to Port Adelaide FC, changed the logo to have black-white stripes, tried to push to have a right to wear the historic black-white stripe jersey more often, and after a decade eventually the broader Adelaide fans adopted PAFC as a second team for all of Adelaide anyway.
Similarly, St George pushed to ensure the Dolphins didn't wear a red V, or even red with a white V (as that's St George's alternate strip), which caused a new color to be added (gold), they dropped Redcliffe in favor of a broader "The", they created a new NRL entity separate from the Redcliffe entity, and they came out with a horrible jersey.
It's only a matter of time before The Dolphins realize all the same things that PAFC did, and take steps to embrace a more defined identity, their own. In time the broader Brisbane fans will embrace the NRL "Redcliffe Dolphins" anyway as a second team for all of Brisbane, wearing their iconic heritage jersey as their default home uniform.
I hope it happens sooner than later anyway. As a Redcliffe Dolphins supporter too, it will be annoying seeing them not be themselves for however long that period of time takes.
