I've defended Guillen here, in some ways, because I don't think that he's malicious. I think he's trying to be funny or contrarian.
That said ... I think that some who think this is political correctness run amok have a fundamental lack of understanding of why this is a big deal for Marlins management. I think this is because most of us have spent either the entirety of our careers or a good portion of our careers as journalists.
We're not bean counters. We put principle over profit, God bless us. And we don't understand why a team's front office would cave to a pack of rabid fans, because that's not how we're wired. That's selling out.
But it's also the way that businesses work. I can understand looking at their actions and thinking, "I would never, ever want to have to do that." But you also have to try to see the self-preservation angle. It's a business.
Now you may find that distasteful or in opposition to your values. But at least try to understand that's what's going on, not necessarily "political correctness run amok." And, once you get that, if you want to rip their ass for selling out, have at it.
But remember that there are consequences, particularly for a franchise that has never drawn particularly well to begin with. And if you're running things there, you have to be willing to deal with those consequences as a result of your principled stand.
