I am going to parse this and first state that you are 100% wrong in your assessment here.
Cheating has always been a part of baseball, even when there are rules against it. Pine tar, spit balls, sign stealing, steroids, speed, pitch tipping pitch framing, etc. When caught people pay their price, and then move on. Cheating to win has always been a part of baseball culture, and while penalized, it is something that has never, and will never go away. The argument has always been how much "cheating" is OK, how much cheating is going to get you in trouble, and how much cheating will get you in a LOT of trouble.
Pete Rose didn't get banned for cheating. He got banned for betting on baseball. THIS has always been the thing to get you a lifetime ban. This goes back to the Black Sox. Playing to LOSE will also get you the ban treatment. Neither of those things happened here. The closest thing Pete Rose did was to tip off the professional gambling world to when he WASN'T willing to bet on his own team. But what he did was ALWAYS known to be a bannable offense. He also followed up his stupidity by flat out lying about it, and being proven a liar even when MLB seemed to be giving him an opening to get out of his mistakes. He might not have gotten banned if he had fessed up when he got this chance.
Now we can definitely sit and argue all day about how bad Hinch's role was in all of this, if his punishment was appropriate and if the Sox should touch him as a manager. But what happened with Pete Rose is not an equitable item to what Hinch did.
