Why am I not surprised that you're the type of person to make up a scenario to get mad about, then get mad about that scenario? On brand.
No one is "accepting" mediocrity. One team can win the WS every year -- one. You've set yourself up nicely to always say we're not trying to win when the Brewers - to the surprise of literally no one - doesn't win the World Series.
Championships absolutely matter. We live in the real world and understand the Brewers have disadvantages. They're still in contention every year and have prospects to send. Last I checked, the deadline hasn't arrived and a deal can still be made. Rather than endlessly complain and and attempt to gaslight us, you could come up with some trade scenarios?
