Not 100% true by any means but most people who watched ESPN and most of the popular sports are men and are usually not the ones who give a crap about more female sportscasters, PC language or whatever when it comes to sports. Not that these guys can't or don't care about these things in general but they want their sports programming to be about sports and nothing else. So I could be way off but that's what I have found.
When you start trying to make a good portion of your programming super PC friendly, LGBT friendly and other smaller group friendly you start pushing away your bread and butter customer.
I stepped away from ESPN for all things except for actual live games after they fired the guy for saying someone finally found the chink in the armor of Jeremy Lin. That told me that they cared more about the possibility of offending a small handful of people than they did about their own employee, a good well written story, or their fans. I would bet 99% of ESPN watchers didnt flinch for a second when the guy said it. That made me back away from everything else because I realized they no longer cared about the sports quality of their reporting.
