You seem to be confusing the reaction to the one email sent ten yrs ago and released a couple days ago to the new ones released yesterday sent to various people that span 8 yrs ending in 2018. But like I said I agree with your take on nfl hypocrisy
So he sent dozens of PRIVATE emails. Or I should say, emails that were meant to be viewed by just the recipients of those emails. In other words, no one was offended by those emails until the NY Times exposed them and told people they need to be offended.
But I have a suspicion that the NFL and/or the Raiders gave him money to walk. If not, I think Gruden could have been a real thorn in the side of the NFL if he had chosen to fight any kind of firing. No one just walks away from $60 million unless they've been given a consolation prize.
But it's a good thing the NFL doesn't take a hard line on criminal activity like they do offensive words. I mean, it would be unfair to hold repeated offender Tyreke Hill accountable for his transgressions like child abuse and domestic violence. He's black, you know.
