I'm sort of in the same boat. I lived (and still live) in Atlanta when he was a Brave and opened his fool mouth.
I don't know whether or not he's evolved on racial or LBGT issues, but he has kept is mouth shut more in the last 15 years. His thing now seems to be cashing in on being a far-right wingnut. His column on WoldNetDaily, for example, probably didn't come along because of his fastball. And his "jews with guns would have prevented the Holocaust" thing must have made Ted Nugent buy up all the old John Rocker jerseys he could find.
I kept waiting for him to go off by himself and vent away from his team while beating his head against a tree. "One of them is BLACK and one of them is GAY and one of them is of INDETERMINATE RACIAL ORIGINS and... oh, she's gone? Cool, but one of them is still GAY..." But no, he mostly behaved himself.
As for the rest, I found them all unusually likable. I never watched TAR so I had no preconceptions about the Twinnies. Everyone else seemed pretty affable. I hope it's a fun season.
